Direct conversion receiver means smaller radars, says ADI

A direct conversion receiver development platform has been designed by Analog Devices for the L- and S-band frequency radar bands.

The AD-FMCOMMS6-EBZ platform is a 400MHz to 4.4GHz receiver (1350MHz to 1650MHz with installed filters) in a VITA57-compliant form factor.

The receiver integrates the AD9652…

GaN technology storms transistor market

Liam Devlin and Andy Dearn describe the design of a 25W X-band gallium nitride (GaN) power amplifier.

Gallium nitride (GaN) technology is very well suited to the realisation of solid-state microwave power amplifiers.

High electron mobility transistors (HEMTs) fabricated on GaN processes have high breakdown voltages, can be…
