  • Good flatness
  • Up to 22 GHz IF
  • Up to 40 dB balance
  • VSWR 2:1 (typ.)
Applications
  • Low noise receivers of mm-wave signal
  • Instruments and test equipment
Description
The Balanced mixers are frequently used as a part of a mm-wave receivers/down converters. Also ELVA-1 offers the rest components of the down converters: High stable local oscillator CIDO series to drive balanced mixer and waveguide filters. Due to the down converters have two received frequency bands lower and higher LO frequency some waveguide filters can be installed at RF port of the Balanced mixer to suppress needless signals.
Typical Block Diagram
Typical appearance and measured data of a receiver/down converter are presented below:

How to order

 Specify Model Number DCBM-XX/LO/IF/N/A/В, where

XX – number of waveguide standard (Ex. 10 for WR-10 and 06 for WR-06)

LO – LO frequency (or operating range), F- if full band

IF  – intermediate frequency range

N  – number of operating harmonic, nothing if N=1

A  – with built-in power amplifier at output, nothing if without output power amplifier

B  – requires bias, nothing if no bias

Examples

DCBM-06/142/6-18 (D-band mixer, LO= 142 GHz, IF= 6-18 GHz

DCBM-10/94/0.5-1.5/A (W-band mixer, LO= 94 GHz, IF= 0.5-1.5 GHz, harmonic number 1, with built-in output power amplifier

Delivery time 6-8 weeks for standard models. Custom designed mixers are delivered within 12 weeks ARO.

All ELVA-1 balanced mixers are warranted by the manufacturer for one year after receipt.
