The HMC680LP4E delivers noise figure of 5 dB in its maximum gain state, with output IP3 of up to +40 dBm in any state. This high linearity DVGA also offers a differential RF output which can be utilized to interface directly with SAW filters in Tx and Rx applications, and with digital to analog converters in Rx chains. The HMC680LP4E is housed in a RoHS compliant 4×4 mm QFN leadless package, and is CMOS/ TTL compatible.
The HMC681LP5E delivers noise figure of 2.8 dB in its maximum gain state, with output IP3 of up to +36 dBm in any state. This serially controlled 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 HMC681LP5E is housed in a RoHS compliant 5×5 mm QFN leadless package, and provides the user with a highly integrated solution. This same functionality is also available with parallel control inputs as the HMC626LP5E.
