MAX2027EUP+D

The MAX2027EUP+D is an IF digitally controlled variable gain amplifier in 20 pin TSSOP package. This high performance, digitally controlled variable gain amplifier is designed for use from 50MHz to 400MHz. The device integrates a digitally controlled attenuator and high linearity IF amplifier in one package. Targeted for IF signal chains to adjust gain either dynamically or as a one-time channel gain setting, the MAX2027 is ideal for applications requiring high performance. The attenuator provides 23dB of attenuation range with ±0.05dB state to state accuracy. It is used in cellular base stations, receiver gain control, transmitter gain control, broadband systems, automatic test equipment and terrestrial links. It has 42dBm 2nd order output intercept point and 34.7dBm 3rd order output intercept point.
