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: 16mm
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
