General Description
Applied Radar, Inc.’s AR1004-2-18-4 Four Channel, 2-18 GHz
RF Downconverter Module provides four channels of RF downconversion with an RF input frequency range of 2 to 18 GHz.
The IF output is centered at 1125 MHz with a 500 MHz bandwidth (875 - 1375 MHz). The module provides typical gains
of 42 dB at 2 GHz and 27 dB at 18 GHz. There is 25 dB
of gain control with four bit resolution (approximately 1.6 dB
steps). The form-factor is a single-slot 6U VME module.
Top view
The AR1004-2-18-4 is a dual conversion downconverter with
four parallel channels. The first LO (LO1) is tunable over
23.63 GHz to 39.63 GHz to select the RF input frequency
desired (LO1 (GHz) = 21.63 GHz + RF (GHz)). The second LO (LO2) is fixed at 22.755 GHz. Both LOs are a single input for all four channels and must be supplied by the
user.
Digital control and status is available through the VME connector or through the front panel USB port. The digital control
board provides power up and power down sequencing, control of variable attenuators, temperature monitoring, monitorBottom view
ing of all amplifier bias currents, and total hours the module
has been powered on. This temperature and current monitoring capability provides a built-in-test (BIT) capability for diagnostic purposes. Basic control and status software is
included.
For a complete receiver solution, including synthesizers for LO1 and LO2, Applied Radar Inc. offers the AR1011 Analog
RF Receiver Unit (ARRU). The AR1011 ARRU is available in a 19-inch rack format which incorporates a 21 slot VME
chassis containing up to sixteen AR1004-2-18-4 modules. The 19-inch rack also accommodates the LO1 and LO2
synthesizers. Other form factors are available upon request; contact our sales department for more information.
