HamGeek Micro PA100 100 W HF Power Amplifier

The Micro PA100 is a compact HF power amplifier for compatible low-power amateur-radio transceivers. It is intended for 50-ohm HF systems where the operator can set the correct drive level, power supply and antenna/load conditions. The front panel provides power and SWR information, while the unit uses automatic TX/RX switching and temperature-managed cooling.

Verified Specifications

• Frequency range: 3.5-30 MHz.
• RF drive: 1-5 W; maximum 7 W.
• Rated output: 100 W +/-1.5 dB at 13.8 V.
• Power input: 10-15 V DC; 13.8 V nominal. Lower supply voltage reduces available output power.
• Current requirement: up to 18 A. Use a suitably rated DC supply and cable.
• RF system impedance: 50 ohms.
• Operating temperature: up to 55 C; dimensions including protrusions: about 132 x 58 x 198 mm; weight: about 1.1 kg.

Operation and Connectivity

• Automatic RF-sensed TX/RX switching can operate without a PTT/SEND connection where the transceiver and installation are suitable.
• Five switched low-pass-filter sections cover the HF amateur bands from 80 m through 10 m.
• Displays output power, SWR, supply voltage and temperature; dual-fan cooling and protection functions support normal operation within the rated conditions.
• The ACC connection supports ICOM, Yaesu and Xiegu band-switching protocols when the appropriate compatible ACC control cable is connected.
• Rear-panel connections are labelled for DC input, ACC, transceiver (TRX) and antenna (ANT). Confirm connector type and pinout before connecting equipment.

Package and Setup Notes

• Package contents: Micro PA100 amplifier and DC power cable. Antenna, transceiver, ACC control cable and DC power supply are not included.
• Set the transceiver drive within the listed range and verify a suitable 50-ohm antenna, feed line and load before transmitting. SWR readings depend on the complete antenna system.
• Use only on frequencies, emission types and power levels permitted by the operator's authorization and local radio regulations.
