The RF Line
UHF Power Amplifier
. . . designed specifically for the Pan European digital 8.0 watt, GSM mobile
radio. Other applications exist in standard analog cellular radios. The MHW912
is capable of wide power range control, operates from a 12.5 volt supply and
requires only 1.0 mW of RF input power.
• Specified 12.5 Volt Characteristics:
RF Input Power — 1.0 mW (0 dBm)
RF Output Power — 12.5 W
Minimum Gain — 41 dB
Harmonics — – 30 dBc Max @ 2.0 fo
• New Biasing and Control Techniques Providing Dynamic Range
and Control Circuit Bandwidth Ideal for GSM
• Low Control Current
• 50 Ohm Input/Output Impedances
• Guaranteed Stability and Ruggedness
• Test fixture circuit board photomaster available upon request by contacting
RF Tactical Marketing in Phoenix, AZ.
