The RF Line

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

Power Gain — 40 dB Typ

Harmonics — – 30 dBc Max @ 2 f0

• Linearity (IMD) — –29 dBc Max for 3rd Order; –34 dBc Max for 5th Order

• New Biasing and Control Techniques Providing Dynamic Range and Control Circuit

Bandwidth Ideal for USDC

• 50 Ω Input/Output Impedances

• Guaranteed Stability and Ruggedness
