The RF Line

UHF Power Amplifiers

. . . designed specifically for portable radio applications. The MHW804 Series is

capable of wide power range control, operates from a 7.5 volt supply and

requires only 1.0 mW of RF input power.

• MHW804–1 — 800 to 870 MHz

MHW804–2 — 896 to 940 MHz

• Specified 7.5 Volt Characteristics:

RF Input Power — 1.0 mW (0 dBm)

RF Output Power — 4.0 W

Minimum Gain — 36 dB

Harmonics — – 45 dBc Max @ 2.0 fo

• 50 Ohm Input/Output Impedances

• Guaranteed Stability and Ruggedness

• Circuit board photomaster available upon request by

contacting RF Tactical Marketing in Phoenix, AZ.
