The HMC626LP5(E) delivers noise figure of 2.8 dB in its maximum gain state, with output IP3 of up to +36 dBm in any state. This single positive control line per bit digital VGA incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. The HMC626LP5(E) is housed in a RoHS compliant 5x5 mm QFN leadless package, and requires no external matching components. A serial control version of this product is available as the HMC681LP5(E).
