Agilent 8766/7/8/9K Microwave Single-Pole Multi-Throw Switches Product Overview dc to 18, 26.5 GHz Features and description • Exceptional reliability, long life (5,000,000 cycles minimum) • Excellent repeatability • Compact • Easy GPIB implementation for ATE applications • Single-pole, multiple-throw models available: three-throw (8766K) four-throw (8767K) five-throw (8768K) six-throw (8769K) This Agilent Technologies family of single-pole, multiple-throw switches utilizes the same proven technology as the well known Agilent 849X family of step attenuators. These products offer the same rugged reliability, excellent repeatability (typically 0.01 dB to 18 GHz and 0.05 dB to 26.5 GHz), long life (greater than 5 million switching cycles), compactness, and broadband performance as the 849X family. Each product consists of 2 to 5 solenoid driven switching sections connected in series. The solenoid armatures are held in place with permanent magnets able to withstand shocks over 10 g’s. The sections switch within 20 milliseconds, including contact settling time, which is of importance for automatic test applications. The switches include self-interrupting contacts which minimize power consumption and simplify the driver circuit design (figure 1). Each model is available with a wide range of solenoid voltage choices (24 volts, standard, or optionally 5 or 15 volts) to match your product or system’s requirements. As a section is switched, the internal contacts of the activated coil open, thus shutting off current flow. At the same time, the internal contacts for the other coil close so that it can be activated when desired. Figure 1 shows a section that has been switched to the RF connector position (note the closed thru line coil contact). The switching is “break-before-make” type, thus a momentary interruption of the RF signal occurs at switching. Section switching Although all sections can be switched simultaneously, the attenuator drive must not allow both pins of the same section (e.g., section 1, pins 5 and 6) to be activated concurrently, or else that section would cycle rapidly. All terminals are “floating,” so bipolar or unipolar power supplies may be used. Figure 1 shows one switching section schematic. Each section utilizes one solenoid with dual coil windings, one coil to switch in the RF connector, and one coil to switch in the thru line. With a positive voltage applied to the common pin, the state (RF connector or thru line) of a particular section is determined by connecting its RF connector pin or thru pin to a negative voltage or ground. Tables 1 through 4 define the pin assignments for the different switches.

A TTL “HI” input to the driver switches in the RF connector, while a “LO” will activate the thru line for that section. This provides a complementary driver for the section which assures that only one solenoid of the pair is activated at a time. Diode protection is required to protect the IC from the solenoid voltage flyback. Switch position can be indicated remotely by utilizing the open and closed states of the internal coil contacts. Figure 1 displays two indicator circuits, one providing a TTL output and one that activates an LED. These circuits will output a TTL “HI” (LED lamp “ON”) if the RF connector is in the RF circuit, and will output a TTL “LO” (LED lamp “OFF”) if the thru line is in the RF circuit. Since current is drawn through the coil for these circuits, inadvertent switching is prevented by limiting the current to 5 mA. LED Inductor Circuit +5V 0.13K Driver (DM7406N*) (DM7404N*) The 11713A includes an integral power supply (with short circuit protection) that can simultaneously provide 125 milliamps at 24 volts to all contacts for control of the atten-uators and switches, so no external power supply is needed. Each 11713A is provided with two (2) plug-in drive cables for the programmable switches to simplify connection to the driver.

The 87130A is a 3.5 inch high, full width system II attenuator/switch driver capable of driving up to 248 bistatic electromechanical switches or attenuator sections. The 87130A is controlled over GPIB via standard commands for programmable instruments (SCPI) commands. The 87130A has been designed for use in both ATE switching systems and computer controlled bench top applications. 4.22K Switch Drive Circuit Inverter IC Relay Driver GPIB attenuator/switch driver Employing programmable Agilent step attenuators and switches in an automatic test system becomes an easy task when the Agilent 11713A or 87130A attenuator/switch driver is specified into the system. The 11713A has all of the necessary features to provide GPIB control of up to ten switching sections of the 8766/7/8/9 series switches (e.g., five 8766s, two 8769s, etc.). 0.62K LED +5V The 11713A also features convenient front panel keys so the user can manually activate the individual switch sections when in the “local” mode. Switching time for the drivers is less than 10 milliseconds.

The input connector “C” is always defined as the connector at the opposite end of the switch from the dc drive cable. Frequency range: dc to 26.5 GHz all models or dc to 18 GHz for Option 876xK-002 (SMA connectors) The output ports are numbered sequentially from the input connector. For example, if an 8768K is being used, use the 8768K table to read isolation to each port. If port three (the third connector from the input) is selected, the isolation to ports 1 and 2 will follow curve A. Isolation to port 4 will follow curve B and isolation to port 5 will follow curve C. Reading from figure 3 at 8 GHz, the worst case isolation to ports 1 and 2 will be 30 dB; to port 4, 45 dB; and to port 5, 65 dB. Note that in selecting ports 1 or 2, isolation to disconnected ports can be varied by choosing the position of each section to “thru” or “on.” The important thing to note is that, depending on the user’s application, port assignments can be important to optimize performance at higher frequencies. All isolation tables refer to figure 3.

It provides room for you to install one single-pole multithrow microwave switch or a programmable step attenuator. The 8766K/8767K/8768K/8769K single-pole, multithrow switches can be installed, providing 3-, 4-, 5-, or 6-throw switching. Alternatively, the 33320G/H, 33321G/H, 33322G/H, and 33323K step attenuators can be installed providing broadband accuracy, high repeatability over a long life, and rapid switching flexibility. Whichever device you choose, you must order each one separately. This module contains the control, drive, and power circuitry for mounting and controlling the microwave switches or step attenuators. It comes with a 14-pin DIP socket for connecting one microwave switch or step attenuator either in the module or remotely. Refer to the Agilent Technologies Website for instrument driver availability and downloading instructions, as well as for recent product updates, if applicable. Documentation Available Please request the Agilent Microwave Test Accessories Catalog for additional information. Cabling For frequencies up to 18 GHz, use a good quality flexible cable and SMA connectors. For frequencies above 18 GHz, use semirigid type cable and APC 3.5 connectors.
