Functional Diagram
Electrical Specications, TA = +25° C, Vdd = Vdd1 = Vdd2 = +5V, Rbias = R1 = 200 Ω [2]
The HMC770LP4BE is ideal for:
• Cellular / PCS / 3G
• Fixed Wireless & WLAN
• CATV, Cable Modem & DBS
• Microwave Radio & Test Equipment
• IF & RF Applications
High Output IP3: +40 dBm
Single Positive Supply: +5V
Low Noise Figure: 2.5 dB [1]
Differential RF I/O’s
20 Lead 4x4 mm SMT Package: 16mm²
The HMC770LP4BE is a GaAs pHEMT Differential
Gain Block MMIC amplier covering 40 MHz to 1
GHz and packaged in a 4x4 mm plastic QFN SMT
package. This versatile amplier 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 gure. Differential I/Os make this amplier ideal
for transimpedance and SAW lter applications, and
in transceivers where the IF path must be handled
differentially for improved noise performance.
Evaluation PCBs are all available with either SMA
(50Ω) or Type F (75Ω) connectors.

Evaluation PCB - 50 Ohm
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 Ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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.
