New Bi-directional SSPA Designed to Support CW/FM and QAM Signals

Triad RF Systems has announced the development of a dual, bi-directional amplifier that supports 2X2 MIMO radio applications. Model TTRM2005D is a solid-state-power amplifier (SSPA) that operates at a frequency of 2.2 - 2.5 GHz. It is designed for military and commercial use and supports a variety of signal types, from simple CW/FM signals to complex, highly modulated carriers such as 64 and 256QAM.

The technical features for each channel on this dual bi-directional amplifier include a transmit signal gain of 25 dB, a receive signal gain of 12 dB, a received signal noise figure of 2.5 dB, and ~20W BPSK power x2 (40W of total RF power). The supply voltage is an ultra-wide 12-30 VDC. 

This SSPA uses the latest LDMOS transistor technology. As a result, it's capable of achieving either highly linear power with low distortion or performing at peak power with extremely high efficiencies. Its operational features include manual or automatic transmit (TX)/receive (RX) switching, temperature monitor output, over-temperature protection, and amplifier status output. It measures 3.4 X 2.6 X 0.65 in. and weighs just 5 ounces, making it the smallest standardized amplifier of its kind.

In addition to MIMO radio, additional applications for this class AB LDMOS SSPA module include other military and commercial radio systems, software-defined radios (SDR), and general-purpose RF amplification. It is capable of supporting any signal type and modulation format, including 3 and 4G telecom, WLAN, OFDM, DVB, QAM, and CW/AM/FM technologies.
