The HMC272MS8 is an ultra miniature single balanced mixer in an 8 lead plastic surface mount Mini Small Outline Package (MSOP) from Hittite Microwave Corporation. This passive MMIC mixer is constructed of GaAs Schottky diodes and a novel planar transformer balun on the chip. The RF port is balanced via the MMIC balun while the LO port is connected directly to the diodes. The HMC272MS8 features ultra small package, high isolation and low loss.
The HMC272MS8 is an ultra miniature passive MMIC mixer constructed of GaAs Schottky diodes and a planar transformer balun. It features an MSOP8 package with LO/IF isolation of 32 dB and an input IP3 of +20 dBm, making it suitable for applications like PCS up/down converters and W-CDMA systems.
The document provides electrical specifications at +25°C, including frequency ranges, conversion loss, noise figure, and various isolation parameters. It also lists absolute maximum ratings such as RF/IF input power of +13 dBm and LO drive of +27 dBm.
