GENERAL DESCRIPTION
The ADRF5130 is a high power, reflective, 0.7 GHz to 3.5 GHz,
silicon, single-pole, double-throw (SPDT) switch in a leadless,
surface-mount package. The switch is ideal for high power and
cellular infrastructure applications, like long-term evolution (LTE)
base stations. The ADRF5130 has high power handling of 43 dBm
(typical), a low insertion loss of 0.6 dB, input linearity of 68 dBm
(typical) third-order intercept, and 0.1 dB compression point
Rev. PrA
(P0.1dB) of 46 dBm. On-chip circuitry operates at a single,
positive supply voltage of 5 V and typical bias current of 1 mA,
making the ADRF5130 an ideal alternative to pin diode-based
switches.
The device comes in a RoHS compliant, compact, 24-lead, 4 mm ×
4 mm LFCSP package.

Preliminary Technical Data
ADRF5130
THEORY OF OPERATION
The ADRF5130 requires a single-supply voltage applied to the
VDD pin. Bypass capacitors are recommended on the supply line
to minimize RF coupling.
The ADRF5130 is controlled via a digital control voltage
applied to the VCTL pin. A small bypassing capacitor is
recommended on these digital signal lines to improve the RF
signal isolation.
The ideal power-up sequence is as follows:
1.
2.
3.
4.
The ADRF5130 is internally matched to 50 Ω at the RF input
port (RFC) and the RF output ports (RF1 and RF2); therefore,
no external matching components are required. The RFx pins
are dc-coupled, and dc blocking capacitors are required on the
RF lines. The design is bidirectional; the input and outputs are
interchangeable.
Connect GND.
Power up VDD.
Power up the digital control input. Powering the digital
control input before the VDD supply can inadvertently
forward bias and damage ESD protection structures.
Power up the RF input. Depending on the logic level
applied to the VCTL pin, one RF output port (for example,
RF1) is set to on mode, by which an insertion loss path is
provided from the input to the output, while the other RF
output port (for example, RF2) is set to off mode, by which
the output is isolated from the input.
