MODEL

DA-26-4, DA-618-4

2-18 GHz, Digital Attenuators

TECHNICAL BULLETIN

Description

Two models are provided, to cover the frequency

range of 2-18 GHz, in two bands: 2-6GHz

(Model DA-26-4) and 6-18Ghz Model DA-618-4).

Both models are 4-bit digitally controlled, with a

dynamic range of 15dB.

The units are designed in microstrip, using PIN

diodes to switch ceramic film resistor elements.

The units have SMA connectors and solder feed-

through bias terminals.

They are intended for military, including airborne,

applications. *(1)
