GPA-2 is a dual-channel 2*2 W TDD RF power amplifier with integrated transmit/receive (T/R) functionality launched by Zencheer. Its compact size is only 69* 58 mm. It operates over the 500-1500MHz band, provides high-linearity output, and can be used with various wireless cards/modules supporting standards such as WiFi, LTE, and DVB-T. GPA-2 is an upgraded version of the EPA-2, compared with EPA-2, it adds an open-circuit detection function on the antenna port, improving overall system reliability.
Key Features
- 2*2 MIMO are supported
- DCDC boost integrated which supports wide input range
- Includes open-circuit detection on the antenna port
- Compact size and lightweight, suitable for handheld device
