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 f
o
• 50 Ohm Input/Output Impedances
• Guaranteed Stability and Ruggedness
• Circuit board photomaster available upon request by
contacting RF Tactical Marketing in Phoenix, AZ.
