Coaxial Relay Switch Matrix for
26.5 GHz RF Systems

ATS-802 coaxial switch DC – 26.5 GHz

ATS-802 Switch Matrix is a multipurpose solution for testing
RF components, wireless devices and specialized antenna
systems. The switch matrix is used for signal routing between
instruments and unit(s) under test (UUT).

Key Specifications
 • Frequency range DC to 26.5 GHz
 • 4 x SP6T (terminated) and 4 x SPDT (failsafe) coaxial relays
 • Power rating 100 W CW @ 2 GHz, 30 W CW @ 26.5 GHz
 • Insertion loss 0.05 dB (typ) @ 4 GHz, 0.5 dB (typ) @ 25 GHz
 • Isolation min. 80 dB (typ) @ DC - 26.5 GHz
 • VSWR ≤ 1.03 (typ) @ 4 GHz, 1.7 (max) @ 26.5 GHz

 • ATE test stations for routing test points to test equipment
 • Microwave signal switching (DC to 26.5 GHz)




 • Built-in 5 V / 5.5 V / 4 A power supply for UUT
 • External power supply switching (50 V / 10 A max)
 • Built-in RF attennuator: 18 GHz, 20 dB, 5 Watt or
   18 GHz, 30 dB, 100 Watt (optional)
 • Wideband RF amplifier (optional)
 • Digital I/O
 • Hardvare based trigger. New technologies and radar applications call for
   considerably faster and often precisely defined path switching intervals.
   The ATS-802 hardware trigger option delivers precise, reproducible and
   accelerated path switching. Up to 16 paths can be controlled,
   depending on the trigger type. A path can consist of just one switching
   relay or a number of switchable elements. The trigger function can be
   programmed using SCPI commands. Since calculating trigger intervals
   for paths containing multiple switching elements is a tedious task, the
   controller offers a very useful feature. It calculates the minimum trigger
   interval for a given path based on the data sheet values of all switching
   elements involved and taking into account the internal delays.
 • Analog inputs (multiplexed), and A/D converter
 • Control interface: USB, Ethernet (optional)
 • Software interface: SCPI
