The MMTR2931P53A operates at 2.7 to 3.1 GHz, with an output power of up to 200 W and a transmission gain of 53 dB. Compared with broadband TR, the narrowband TR has higher gain and lower noise figure, and performs better in applications such as radio communications and radar. The MMTR2931P53A is designed with our gallium nitride (GaN) high electron mobility transistor (HEMT), which has higher breakdown voltage, wider bandwidth and higher efficiency. The MMTR2931P53A is equipped with a circulator that provides duplexing function and a limiter for protecting the receiver. In addition, it also contains timing circuits. The MMTR2931P53A is manufactured using Mars RF's advanced gallium nitride (GaN) technology, which has higher power density, efficiency, wider bandwidth and efficient thermal management.

GaN is quickly becoming the semiconductor material of choice for many transistor applications. GaN has high electron mobility, supports greater gain at higher frequencies, and has higher efficiency than equivalent LDMOS (laterally diffused MOSFET) technology. The use of GaN transistors supports key RF requirements such as high gain, low power consumption, high throughput, and extremely fast switching speeds. In addition, GaN transistors enable numerous systems such as air traffic control to span the L, S, C, X, and Ku bands. Gallium nitride transistors can handle a wider temperature range than traditional transistors and work well in harsh environments, making them ideal for RF applications.
