RFHIC has reduced the size of two of the company’s 8 W GaN hybrid power amplifier (PA) modules, making them 50 percent smaller than the previous designs - optimal for 5G massive MIMO and small cell base stations.

The RPAM35008-25 covers 3.4 to 3.6 GHz (200 MHz in band n78), delivering 8 W (39 dBm) average output power and 45 percent power-added efficiency (PAE) with a 7 dB peak-to-average ratio waveform. The PA has a saturated output power of 47 dBm and 25 dB gain. The RPAM37508-25 covers 3.7 to 3.8 GHz (100 MHz in n78) and provides the same performance.

Both PAs are two-stage Doherty designs, using GaN in both amplification stages, and are fully-matched to 50 Ω, requiring minimal external components. The PAs are assembled in plastic QFN surface-mount packages and have excellent thermal performance and a much smaller footprint compared to other modules on the market.

The high PAE of these PAs improves base station power consumption, reducing the operating costs for the service provider. The efficiency also eases base station thermal design, critically important for meeting the size constraints of small cells and massive MIMO antennas.

For other frequencies and power levels, RFHIC can customize these designs to meet unique customer needs.

For more than 20 years, RFHIC has been committed to providing the highest quality GaN transistors, PAs and subsystems for telecom, military and ISM applications.
