Bi-directional SSPA Supports CW/FM and QAM Signals

November 19, 2020

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 2,200-2,500 MHz. 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 includes a transmit signal gain of 25 dB, a receive signal gain of 12 dB, a receive signal noise figure of 2.5 dB, and ~20W BPSK power x2 (40W of total RF power). Supply voltage is an ultra-wide 12--30 VDC. It 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.
