The CHM1190 is a balanced Schottky diode mixer based on a six quarter wave ring structure. It could be use in receiver or transmitter part. This circuit is manufactured with the BES- MMIC process: 1 µm Schottky diode device, air bridges, via holes through the substrate, stepper lithography. An electrically identical chip with a mirror drawing versus de LO side is available under the part number CHM1191. These two MMICs could be helpful in a TX, RX architecture module. It is available in chip form.
The CHM1190 is a balanced Schottky‑diode mixer built with a six‑quarter‑wave ring structure for use in receiver or transmitter modules. It operates over a 22‑24 GHz local‑oscillator range and provides an IF output from 1 to 3 GHz.
Key specifications include a typical conversion loss of 7 dB at 7 dBm LO power, 30 dBc LO/RF isolation, and a compact chip size of 1.73 mm × 1.53 mm × 0.10 mm. Ordering information and mechanical data are provided for integration into RF designs.
