The TTRM4302 from Triad RF Systems is a Bi-Directional Amplifier that operates from 5000 to 6000 MHz. In Tx mode, it delivers a saturated output power of 10 W (40 dBm) with a gain of 25 dB while in Rx mode, it provides a gain of 15 dB and has a noise figure of 2.5 dB. This class AB amplifier supports manual or automatic Tx/Rx switching and has a switching time of less than 2 µs. It uses GaN transistor technology to achieve high linearity with low distortion, or peak power at high efficiencies. The amplifier is designed to support signal types from simple CW/FM signals to complex, highly modulated carriers such as 64 and 256 QAM for 3G/4G telecom and WLAN applications. It features over/under/reverse voltage protection and also provides over-temperature protection.
The TTRM4302 requires a DC supply from 10 to 30 V and consumes 1.2 A of current in Tx mode and 100 mA of current in Rx mode. It employs the latest RF simulation and design methods to achieve low size, weight, and DC power consumption. This amplifier is available in a module that measures 2.30 x 2.30 x 0.45 inches with SMP connectors and is suitable for use in commercial/military radio systems, software-defined radios (SDR), and general-purpose RF amplification applications. It has an operating temperature range from -40°C to +85°C and provides protection against shock/vibration according to MIL-STD-810 or equivalent standards.
