HMC144

v01.0801 MICROWAVE CORPORATION HMC143 / HMC144 GaAs MMIC DOUBLE-BALANCED MIXER, 5 - 20 GHz Typical Applications The HMC143 & HMC144 is ideal for: • Microwave Pt to Pt Radios • VSAT Features Input IP3: +21 dBm LO / RF Isolation: 30 dB IF Bandwidth: DC to 3 GHz Small Size: 1.48mm x 2.06mm Functional Diagram General Description The HMC143 chip is a minature double-balanced mixer which can be used as an upconverter or downconverter. The chip utilizes a standard 1um GaAs MESFET process. The HMC144 is identical to the HMC143 except that the layout is a mirror image designed to ease integration into image-reject mixer modules. Broadband operation and excellent isolations are provided by on-chip baluns, which require no external components and no DC bias. The design is similar to the HMC141/142 mixers but with an IF combiner in a double-balanced design, providing improved RF/IF isolation. These devices are much smaller and more reliable replacements to hybrid diode mixers. 5 MIXERS - CHIP Electrical Specifications, TA = +25° C, LO Drive = +20 dBm Parameter Frequency Range, RF & LO Frequency Range, IF Conversion Loss Noise Figure (SSB) LO to RF Isolation LO to IF Isolation IP3 (Input) IP2 (Input) 1 dB Gain Compression (Input) 28 14 16 42 5 Min.
