Designed specifically for the European Digital Extended Group Special
Mobile (GSM) Base Station applications in the 925–960 MHz frequency range.
MHW916 operates from a 26 Volt supply and requires 15.5 dBm of RF input
power.
• Specified 26 Volt Characteristics
RF Input Power: 15.5 dBm Max
RF Output Power: 16 Watts at 1.0 dB Compression Point
Minimum Gain: 26.5 dB
Harmonics: –35 dBc Max at 2Fo
• 50 Ω Input/Output System
• Meet GSM Linearity Specification for Base Station up to
12.5 Watts
