HMC558A

Data Sheet FEATURES Conversion loss: 7.5 dB typical at 5.5 GHz to 10 GHz Local oscillator (LO) to radio frequency (RF) isolation: 45 dB typical at 5.5 GHz to 10 GHz LO to intermediate frequency (IF) isolation: 45 dB typical at 10 GHz to 14 GHz Input third-order intercept (IIP3): 21 dBm typical at 10 GHz to 14 GHz Input P1dB: 11.5 dBm typical at 10 GHz to 14 GHz Input second-order intercept (IIP2): 55 dBm typical at 10 GHz to 14 GHz Passive double-balanced topology Wide IF bandwidth: dc to 6 GHz 12-lead ceramic leadless chip carrier package APPLICATIONS Point to point microwave radios Point to multipoint radios Military end use Instrumentation, automatic test equipment (ATE), and sensors GENERAL DESCRIPTION The HMC558A is a general-purpose, double-balanced mixer in a leadless RoHS compliant SMT package that can be used as an upconverter or downconverter between 5.5 GHz and 14 GHz. This mixer is fabricated in a gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) process, and requires no external components or matching circuitry. 5.5 GHz to 14 GHz, GaAs MMIC Fundamental Mixer HMC558A FUNCTIONAL BLOCK DIAGRAM HMC558A LO RF 15000-001 IF Figure 1. The HMC558A provides excellent LO to RF and LO to IF isolation due to optimized balun structures, and operates with LO drive levels as low as 9 dBm. The RoHS compliant HMC558A eliminates the need for wire bonding, and is compatible with high volume surface-mount manufacturing techniques. Rev. C Document ...
