Millimetre-wave SDLVAs from Link Microtek offer high sensitivity

Manufactured by Endwave Corporation, the devices are ideal for use in early-warning and ELINT receivers, DF radar systems and other radar and missile-guidance systems.

The SDLVAs are available in three full and partial band configurations, covering 18-40GHz (part number ASDA-81840), 18-26GHz (ASDA-81826) and 26-40GHz (ASDA-82640), all of which are hermetically sealed using a laser weld process and deliver stable thermal performance from -45 to +85degC.

Typical tangential signal sensitivity is specified as -65dBm @ 85degC (30MHz video bandwidth), and the devices typically have a dynamic range in excess of 69dB. Log linearity and frequency flatness are less than +/-1.0dB and +/-1.5dB respectively.

The SDLVAs are enhanced derivatives of the 18-40GHz DLVA products that were added to Endwave’s portfolio following its recent acquisition of ALC Microwave.
