Broadband Digital Attenuator


HXIs HDA040-069 Digital Attenuator covers the range from DC to 40 GHz in 6-bit operation. Attenuation bit values are 0.5 dB (LSB), 1, 2, 4, 8 and 16 dB for total attenuation of 31.5 dB above the attenuator insertion loss. Low bit errors and
RMS phase errors are characteristics of this attenuator. The attenuator is useful for
communication systems, radars and in test equipment.

Harmonic Mixers


HXI’s HHM series broadband harmonic mixers covers full waveguide bands from 18 – 110 GHz. They utilize a low loss finline structure mated to a GaAs Schottky beam lead diode for minimum conversion loss and maximum bandwidth. The millimeter wave RF frequency is downconverted (using a low cost microwave LO) to a lower frequency, which can in turn interface with a spectrum analyzer or frequency counter.
Three terminal mixers (waveguide RF, coaxial IF port, coaxial LO port) units are available for systems without an internal diplexer.
