HMC188MS8

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.

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.

- Pin count: 8 pins (MSOP/MS8 package)
- Function: GaAs MMIC RF mixer (used for RF/LO-to-IF mixing; ports typically RF, LO, IF plus power and ground in an 8-pin package)

Manufacturer: Analog Devices, Inc. (originally Hittite Microwave; HMC188MS8 is from the HMC RF/Microwave line now owned by ADI).
About the company: Analog Devices is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and RF/microwave integrated circuits for communications, aerospace/defense, instrumentation, and related markets.

HMC188MS8 is a microwave mixer IC. Typical applications include:
- RF/microwave up/down-conversion in wireless, satellite, and radar systems
- Balanced/mixer-based front-ends for heterodyne receivers/transmitters
- LO interfaces and frequency-synthesis front-ends
- Test and measurement equipment and lab prototypes
- Microwave backhaul and point-to-point RF links
(Use depends on the exact RF/microwave frequency range of the part; refer to the datasheet for specifics.)
