EAST BRUNSWICK, NJ – Triadic radio frequency systems 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 2200-2500 MHz. It is intended 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 per-channel specifications of this dual bi-directional amplifier include 25 dB transmit signal gain, 12 dB receive signal gain, 2.5 dB receive signal noise, and ~20 W BPSK power x2 (40 W total RF power) . The supply voltage is an ultra wide 12–30 VDC. It uses the latest LDMOS transistor technology. As a result, it is able to achieve either highly linear power with low distortion or operate at peak power with extremely high efficiency. Its operational features include manual or automatic transmit (TX)/receive (RX) switching, temperature monitoring output, overheat protection, and amplifier status output. It measures 3.4 X 2.6 X 0.65 inches and weighs only 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 (SDRs), 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.
