UHF Linear Power Amplifiers
Designed specifically for the United States digital 3.0 W, mobile radio. The
MHW927A / B are capable of wide power range control, operate from a 12.5 V
supply and require 1.0 mW of RF input power.
•
MHW927A Operates from a 9.5 Volt Bias Supply (VB)
MHW927B Operates from a 8.0 Volt Bias Supply (VB)
•
Specified 12.5 Volt Characteristics for MHW927A/B:
RF Input Power — 1.0 mW (0 dBm) Max
RF Output Power — 6.0 W
