RigExpert 2.1GPA-LD Bidirectional RF Amplifier provides transmit and receive amplification across 2110–2200 MHz for compatible low-voltage communication systems. It combines 13–15 dB transmit gain with 12–13 dB receive gain and automatic VOX-based switching. The compact module operates from a nominal 5 V supply and supports integration into SDR equipment, IoT devices, UAV communication systems and laboratory test installations.
Published measurements specify 2.58 W continuous-wave output and 2.85 W pulse output at 2150 MHz with +20 dBm input. Laboratory testing was conducted with a 5.00 V supply at +22°C. These figures describe specific operating conditions, not guaranteed output at every frequency or installation temperature. Keep the CW and pulse ratings separate when selecting the amplifier for the intended waveform and duty cycle.
Signal-triggered VOX switching changes the amplifier between receive and transmit operation without routine manual changeover. Adjustable sensitivity allows the switching threshold to be matched to the application, although the published listings do not specify the adjustment method. The stated RF input range is 3–20 dBm, with 20 dBm also listed as the standard maximum. Check the connected radio’s output before applying drive.
RigExpert 2.1GPA-LD uses MMCX RF connectors and passive cooling for installation within a larger system. The recommended supply range is 4.75–5.25 V DC, with published consumption of 10 W in transmit mode and 0.4 W in receive mode. Allow for heat dissipation, suitable power wiring and secure mechanical support when planning the enclosure. Published listings identify ESD protection and EMI shielding, but these features do not replace appropriate handling and installation practices.
