Product introduction:

The GF038018Q2 programmable amplifier chip adopts GaAs technology, integrates an amplifier and a digital attenuator internally, with a frequency coverage range of 0.8-18GHz. It can not only achieve gain amplification but also gain adjustment, with an attenuation range of 0 to 30dB and a step size of 1dB. The digital attenuation chip adopts 0/+5V voltage control and is housed in a ceramic package, suitable for SMT surface mount technology.
