HMC448 v01.1007 GaAs MMIC x2 ACTIVE FREQUENCY MULTIPLIER, 19 - 25 GHz OUTPUT Typical Applications Features The HMC448 is suitable for: Output Power: +11 dBm 2 Clock Generation Applications: Wide Input Power Range: -4 to +6 dBm SONET OC-192 & SDH STM-64 Fo, 3Fo Isolation: >20 dBc Fout= 20 GHz Point-to-Point & VSAT Radios 100 KHz SSB Phase Noise: -135 dBc/Hz Test Instrumentation Single Supply: 5V 48 mA Military & Space Die Size: 1.16 x 1.20 x 0.1 mm Functional Diagram General Description The HMC448 die is a x2 active broadband frequ- ency multiplier chip utilizing GaAs PHEMT technology. When driven by a 0 dBm signal, the multiplier pro- vides +11 dBm typical output power from 19 to 25 GHz. The Fo and 3Fo isolations are >22 dBc up to 22 GHz. This multi-rate frequency multiplier can be used in the generation of a half rate clock for 40 Gbps sys- tems or as part of a multiplier chain to generate a full rate 40 Gbps clock. The HMC448 is also ideal for use in LO multiplier chains for Pt to Pt & VSAT Radios yielding reduced parts count vs. traditional approaches. The low additive SSB Phase Noise of -135 dBc/Hz at 100 kHz offset helps maintain good system noise performance. All data is with the chip in a 50 ohm test fi xture connected via 0.076 x 0.0127 mm (3mil x 0.5mil) ribbon bonds of minimal length 0.31mm (<12mils).
