Model: A-1G18G-205N-13P

PMI Model No. A-1G18G-205N-13P is a high performance, high intercept point, multi-octave, wide bandwidth, 50-Ohm matched, ultra-low noise amplifier designed using state-of-the-art GaAs PHEMT devices.  This amplifier is built using advanced hybrid MIC techniques for reliability.  Low input and output VSWR across the band allow the unit to be easily integrated into systems.  The amplifier is built in a compact aluminium allow housing with four mounting holes to facilitate balance mounting to improve contact for heat transfer between chassis and heat sink.
