A miniature frequency mixer is useful for downconverting K-band radar signals to an IF bandwidth from DC to 13 GHz.
Model P1M29B3-2208F is a compact frequency mixer from Spacek Labs that translates K-band signals (typically 26 to 40 GHz) to intermediate-frequency (IF) bandwidths to 13 GHz. The double-balanced mixer, which is optimized for spurious rejection of better than -30 dBc for an RF input level of -10 dBm, is available as a passive mixer or can be specified as an active mixer with amplification on any of the ports. As an active mixer, it provides 10-dB conversion gain with 3.5-dB maximum noise figure. The PM series mixer measures just 1.0 x 12.6 x 0.3 in.
