RACK MOUNT PHEMT PREAMPLIFIERS
TWR1 PHEMT preamplifiers are mounted on a 1.75" H x 19" W (1RU) panel, and include
a 0-10dB attenuator and 110 or 220 VAC to +11-18 VDC power supply. Bandwidth
is approximately 10% of operating frequency for each unit. Gain window is
factory adjustable between limits shown.
