Overview
Description
The HMC188MS8 is a broadband GaAs MMIC mixer from Hittite Microwave (now Analog Devices), packaged in an 8-lead MS8 surface-mount package. It serves as a frequency translator by mixing RF with a local oscillator (LO) to produce an intermediate frequency (IF), or for upconversion depending on port usage. The RF/LO/IF ports are typically 50-ohm matched and the part requires external LO drive and matching networks. It’s used in compact RF/microwave front-ends for communications, radar, instrumentation, and similar systems. Key performance depends on the exact variant and external matching (conversion loss, isolation, IP3, and bandwidth). For precise frequency range and specs, consult the HMC188MS8 datasheet and reference designs.
Equivalent
Cross-refs depend on frequency, LO drive, and IF. HMC188MS8 is a GaAs MMIC mixer in an 8-pin MSOP package. To provide exact equivalents, please specify: (1) RF frequency range, (2) LO drive level/frequency, (3) IF bandwidth, and (4) preferred vendors (ADI, MACOM, Qorvo, Mini-Circuits). With that, I can give matched parts and cross-reference numbers.
