MHW910
UHF Silicon FET Power Amplifier
Designed specifically for the European Digital Extended Group Special
Mobile (GSM) Base Station applications in the 925–960 MHz frequency range.
MHW910 operates from a 24 volt supply and requires 17 dBm of RF input
power. It includes a micropower voltage regulator in the biasing circuit. This
allows MHW910 to operate from any bias voltage between 8 and 28 volts.
