Variable Analogue
Phase Shifter
25.5-32.5 GHz

Product Datasheet

Ka-PS-2533

A MMIC analogue phase-shifter enabling 360ᵒphase variation in the 25.5–32.5 GHz frequency
band.

Overview

This phase shifter provides very low insertion
loss variation over all phases and frequencies(±2 dB) as well as excellent phase tracking over
all frequencies (less than ±25ᵒ). It also offers
an alternative to digital phase-shifters where
any required phase delay is achievable with thephase set by varying the control voltage (VD) inthe range of -0.5 to 0.7 V.

•••••

As the underside of the die is gold plated, thisMMIC is compatible with precision die attach
methods, as well as thermo-compression andthermosonic wire bonding, making it ideal for
MCM and hybrid microcircuit applications.

Connection Configurations

General Notes On Assembly

Die should be mounted on conductive material such as gold-plated metal toprovide a good ground and suitable heat sink, if necessary.
1. Attaching the die using Au/Sn preforms is preferable. The Eutectic
melt for Au/Sn occurs at approximately 280 oC so the die (plus mountand preform) is initially heated up to 180 oC and then it is heated forapproximately 10 seconds to 280 oC using a nitrogen heat gun. The
device will survive 10 seconds at this temperature. The static breakdownfor GaAs devices is approximately 330oC.
2. Pure, dry nitrogen should be used as the heat source.
3. If the device cannot be lifted/ placed by a vacuum device, then ESD dielifting tweezers are preferable.
4. Aluminium wire must not be used.
