HL9323 Sampler / Harmonic Mixer with Differential Input

The HL9323 is a high-precision sampler / harmonic mixer that offers better than -60 dBc linearity in the second and third harmonics up to 20 GHz (RF).

Designed with military, aerospace, and other high-performance applications in mind, the HL9323 offers unparalleled performance in a compact package.

This product has a differential input, so HYPERLABS recommends using a high-performance balun such as the HL9402 alongside this product. Its sister product, the HL9313, has a balun built in.
