With an excellent third order input intercept point and superb dynamic range, these VVAs are ideal for automatic power leveling/gain control circuits in 3G/4G LTE and WCDMA cellular base stations, IF chains, radar, and Satcom systems, as well as broad market wireless systems including military communication transceivers, S-Band radar, and VSAT. The attenuators consist of a pair of matched PIN diodes that terminate two ports of the internal 90-degree hybrid coupler, and are housed in a MCM 8-pin 4.9 x 3.2 x 1.0 mm package.
