Bi-Directional SSPA
Model TTRM2005D is a dual, bi-directional amplifier that supports 2X2 MIMO radio applications. This solid-state power amplifier (SSPA) operates at a frequency of 2200 to 2500 MHz. It is designed for military and commercial use and supports a variery of signal types, from simple CW/FM signals to complex, highly modulated carriers such as 64 and 256QAM. Per channel features on this dual bi-directional amplifier include 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 to 30 VDC and is 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” and weighs just five 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.
