REV 1.1 Page 1 of 8 Copyright © 2020 The FMAM5085 is a Class AB high power amplifier that operates in L and S bands from 1000 MHz to 2500 MHz and generates 20 Watts (typ) of CW RF power. The module utilizes the latest Gallium Nitride (GaN) semiconductor technology with 50% power added efficiency. The amplifier package design features a small form factor of 3.9in³ that’s ideal for size, weight, and power (SWaP) constrained applications used in broadband RF telemetry, tactical communication, electronic warfare, and unmanned aircraft systems, as well as software defined radios. Impressive typical performance includes 13.5 dB of linear gain, 1.8:1 VSWR, +41 dBm third order intercept point, and low harmonic suppression of -24 dBc. Additionally with a nominal 1 Watt RF input level, the amplifier provides 10 dB of gain across the full frequency band. Operating voltage is +28 Vdc with 2.2A of DC current. Additional features include overvoltage protection, reverse voltage protection, and logic on/off control. The rugged Mil-Grade assembly supports female SMA RF input/output connectors and a micro-D 9 pin socket command control connector with an accessory cable assembly included. The operating baseplate temperature range is -40°C to +85°C and the unit is guaranteed to withstand up to 95% relative humidity, altitude levels up to 30,000 ft, and random vibration and shock profiles (see chart below). Pasternack also offers an accessory Harmonic filter option, model FMHFL0000 that can be used at the output of the FMAM5085 power amplifier. This lowpass RF filter has low insertion loss with power handling up to 50W and specifically designed to reduce harmonics at the output of transmitters operating at up through L & S Bands and offers rejection levels of greater than 25 dB from 3.25 GHz to 5 GHz. The filter is offered in a miniature SMA connectorized package.

Confirm that proper ESD precautions and controls are always in place before handling any Amplifier module. 2.) Confirm adequate thermal management is in place to effectively dissipate heat away from the Amplifier package. The Amplifier operational baseplate temperature must be within the operational temperature range stated in the Amplifier datasheet. Depending on the design and thermal requirements, using a heatsink with cooling fan is always recommended for safe reliable operation. A heat sink without a cooling fan may also be used. Damage caused from overheating will void the warranty. 3.) Confirm adequate system grounding is established. The DC power supply and Amplifier must have a common ground in order to operate properly. 4.) Power Amplifiers may require additional DC Current when initially powered- up. Depending on the design, the input current draw could range from an additional 10% to 100% above the maximum rated DC current of the Amplifier. This varies based on product part number. 5.) Confirm the DC power supply, if limited, is set to allow for additional start-up current that’s rated for the Power Amplifier. 6.) Confirm the system is designed and calibrated for 50 ohms. Any impedance mismatch may cause performance issues. 7.) Perform a CALIBRATION (if required) with the loads before connecting the Amplifier to the Network Analyzer to ensure proper performance. 8.) Use a fixed attenuator between the signal source and input port of the Amplifier to optimize the input VSWR match. 9.) Confirm the input power level at the input port of the amplifier does not exceed the maximum rated limit for input power (as stated in the Amplifier datasheet). Pin for Small Signal Gain = P1dB-SSG-10 dB Pin for P1dB = P1dB-SSG+1 dB 10.) Confirm the Network Analyzer is always connected to the Amplifier first before DC power is applied to the Amplifier. 11.) As long as the input and output ports of the amplifier are connected to a 50Ohm load and RF signal power is applied, the Amplifier can be powered up with DC voltage. 12.) Confirm the Amplifier output load is matched for a 50 Ohm impedance and will not exceed the maximum rated VSWR or Return Loss limit for the Amplifier. Exceeding the maximum rated VSWR or Return Loss limit will result in reflected signal power that could damage the Amplifier and void the warranty. 13.) Power Amplifier connected to an Antenna for signal transmission - It’s strongly recommended to use a high power fixed attenuator pad or an Isolator between the output port of the Amplifier and input port to the antenna. Any reflected signal power due to impedance mismatch will likely damage the Amplifier and void the warranty. 14.) The attenuator or isolator used at the output port of the Amplifier must be rated to handle the output power level and operational frequency band of the amplifier. FMAM5085 DATA SHEET
