GT Microwave - Voltage Controlled Attenuators

G.T Microwave Features:

Frequency Ranges: From 250 MHz to 24 GHz any optimized bandwith is available.

Voltage Controlled: 0 Volts = insertion Loss (zero attenuation) to +10 Volts = Maximum attenuation. Linearized models upon request.

High Speed Switching: Attenuators listed are measured from any set value to any value. Switching speeds to 300 nSEC are available upon request.

Low DC Power Consumption: Attenuators require ±15VDC, ±1% @ ±50mA

Stable Attenuation: Variation vs Temperature from -55% to 85°C is typically ±10% of the set value. Linearized models upon request.

Standard Interfaces: RF port connectors are ‘SMA’, female per MIL-C-39012. Control connections are solder terminals. Call factory for optional connectors.
