Bidirectional 2.4G 4W Signal Amplifier 2.4GHz SMA RF Power Amp For RC Drone Image Transmission WiFi Receiver/Transmitter Booster

GCM2627 2.3-2.7GHz 4W Bidirectional Amplifier – CNC Housing, SMA Interface for Drone FPV, LoRa, WiFiImportant Notes:Do not connect both power ports simultaneously. Choose either USB Type‑C (5V fixed) or DC2.5×0.7 (7–28V).Do not operate without an antenna connected to the ANT port – otherwise the amplifier may be damaged.Device port connects to your radio/router/RF module. Antenna port connects to the antenna.Do not exceed absolute maximum ratings.type--c cable And power supply is not includedProduct Description:The GCM2627 is a TDD bidirectional power amplifier based on the GCM2627 amplifier chip, operating from 2.3 to 2.7GHz with a maximum output power of 4W (36dBm). It is designed for drone video/data link range extension, LoRa, WiFi signal boosting, and other RF applications. The module features independent TX and RX paths with 15dB gain each, automatic TDD switching (threshold 0dBm), and fast switching time of 100ns. Housed in a rugged CNC aluminum cavity with SMA connectors, it offers two power input options (USB Type‑C or DC2.5×0.7 jack).Key Specifications:ParameterValueFrequency Range2.3 – 2.7 GHzSaturated Power (Psat)36dBm (4W)TX Gain15dB (typical)RX Gain15dB (typical)Max TX Input Power20dBmSwitching Threshold0dBm (device side)Switching Time100ns (minimum)EVM1.14% @ 23dBmPower SupplyUSB Type‑C: 4.5–5.5V OR DC2.5×0.7: 7–28V (use only one, do not connect both)Current Consumption (RX)0.146A @ 5VCurrent Consumption (TX)0.79A @ 5V (15dBm out), 1.13A @ 5V (30dBm out), 1.5A @ 5V (35.8dBm out)Weight75gConnectorsSMA female (outer thread, inner hole)EnclosureCNC machined aluminum cavityLED IndicationGreen = RX, Blue = TXApplications:Drone video/data link range extensionLoRa / WiFi signal boostingRF front‑end for 2.4GHz band communicationAmateur radio (HAM) amplificationIndustrial wireless equipmentActual measurement chart:1: Connection diagram between testing equipment and GCM2627 bidirectional power amplifierTest equipment: KEYSIGHT N5182B, KEYSIGHT N9020B2: Constellation chart, EVM measurement chartEVM 1.38% @20dBmEVM 1.14% @23dBmEVM 2.09% @26dBmEVM 3.25% @27dBm3: EVM Comparison Table
