HMC351S8 is a double balanced mixer from Hittite Corporation. It works in the frequency range of 0.7-1.2GHz and has a maximum input power of +25dBm. It has a conversion loss of 9dB and a LO/RF isolation of 42dB.
This document describes the Hittite HMC351S8, a GaAs MMIC high IP3 double-balanced mixer covering 0.7 - 1.2 GHz at the RF and LO ports and DC - 0.3 GHz at the IF port. The passive GaAs schottky diode mixer implements planar on-chip baluns and requires no external components, and it can be used as an upconverter, downconverter or modulator. Typical performance given for LO = +19 dBm and IF = 100 MHz includes 9 dB conversion loss, 42 dB LO to RF isolation, 35 dB LO to IF isolation, +25 dBm input IP3 and +48 dBm input IP2.
The datasheet lists electrical specifications, absolute maximum ratings, an outline drawing and evaluation PCB information. The mixer is supplied in an 8 lead plastic surface mount package and is stated to be suited to cellular basestations, cable modems and fixed wireless access systems. Curves show conversion gain versus temperature and LO drive, isolation, return loss, IF bandwidth, upconverter performance, P1dB, IP3 and IP2, along with MxN spurious output and LO harmonic tables.
