WA02 is a wideband low-noise amplifier module based on the NXP BGA2869 chip, featuring extremely wide operating frequency range and excellent input impedance matching performance. It provides high and flat gain while maintaining very low noise figure, and adopts a compact shielded enclosure with standard SMA interface design, making it very easy to integrate into various RF systems as a preamplifier or signal enhancement module. Widely applicable to CATV signal distribution and amplification, satellite LNB (low noise block downconverter) IF signal amplification, wireless communication system testing and development, ISM band (industrial, scientific, medical) weak signal enhancement, and as a basic gain module in general RF laboratories.
Frequency range: DC to 2.2 GHz Gain: typical 31.7 dB (chip); measured approx. 30.5 dB @ 950 MHz Noise figure: typical 3.1 dB @ 950 MHz Output P1dB: typical 10 dBm @ 950 MHz Power supply & current: +5V (range 4.5–5.5V), operating current 19 mA Interface & impedance: 50 Ω internal matching, SMA-K RF connector
