Functional Diagram
General Description
The HMC770LP4BE is a GaAs pHEMT Differential Gain Block MMIC amplifier covering 40 MHz to 1 GHz and packaged in a 4x4 mm plastic QFN SMT package. This versatile amplifier can be used as a cascadable IF or RF gain stage in both 50 Ohm and 75 Ohm applications. The HMC770LP4BE delivers 16 dB gain, and +40 dBm output, with only 2.5 dB noise figure. Differential I/Os make this amplifier ideal for transimpedance and SAW filter applications, and in transceivers where the IF path must be handled differentially for improved noise performance. Evaluation PCBs are all available with either SMA (50) or Type F (75) connectors.

The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
