HMC277MS8 / 277MS8E v00.0906 MIXERS - SGL-BAL - SMT 9 GaAs MMIC SMT SINGLE BALANCED MIXER, 0.7 - 1.2 GHz Typical Applications Features The HMC277MS8 / HMC277MS8E is ideal for: Passive Topology • Cellular / 3G Infrastructure LO / RF Isolation: 26 dB • Basestations & Repeaters Input IP3: +21 dBm • GSM, CDMA & WCDMA Low Conversion Loss: 9 dB • Subscribers & Portables RoHS Compliant MSOP-8 Package Functional Diagram General Description The HMC277MS8 & HMC277MS8E are general purpose single balanced mixers in 8 lead plastic surface mount Mini Small Outline Packages (MSOP). This passive MMIC mixer is constructed of GaAs Schottky diodes and a novel planar transformer balun on the chip. The HMC277MS8(E) requires no external matching components, and is ideal for upconverter and downconverter applications. The RF port is balanced via the MMIC balun while the LO port is connected directly to the diodes. This product is pin for pin compatible with the HMC272MS8(E) which operates from 1.7 to 3.0 GHz.
