HT004B is an experimental RF low-noise amplifier (LNA) designed for high performance and flexible applications, featuring convenient power interface, moderate gain adjustment, excellent IP3 protection and ultra-low noise figure. Its modular design is easy to integrate, amplifying weak signals while resisting strong interference and maintaining stable performance, making it ideal for improving RF front-end signal quality. Can be used as a preamplifier or antenna amplifier for wireless communications, radar detection, medical electronics, research experiments, prototyping and system integration. It can also be paired with SA6 spectrum analyzer, antennas (band-matched such as 1MA2-3G), attenuators and other equipment for walkie-talkie, radio and other RF signal enhancement and testing.
Frequency range: 1 MHz–1000 MHz Gain: 20 dB Supply voltage: 12 V Key features: ultra-low noise figure, high IP3 protection Dimensions & weight: 14 × 10 × 4 cm / 0.12 kg
