Link Microtek introduces SDLVAs for radar systems
Link Microtek
SDLVAs
Link Microtek has released a range of millimetre-wave SDLVAs (successive detection log video amplifiers) that offer good tangential signal sensitivity and dynamic range.
The SDLVAs, manufactured by Endwave, are ideal for use in early-warning and Elint receivers, DF radar systems and other radar and missile-guidance systems.
They 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 with a laser-weld process and deliver stable thermal performance from -45 to +85C.
Typical tangential signal sensitivity is specified as -65dBm at 85C (30MHz video bandwidth).
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 updated versions of the 18-40GHz DLVA products.
