HMC448LC3B SMT GaAs MMIC x2 ACTIVE FREQUENCY MULTIPLIER, 20 - 25 GHz OUTPUT Typical Applications Features 6 The HMC448LC3B is suitable for: Output Power: +11 dBm • Clock Generation Applications: SONET OC-192 & SDH STM-64 Wide Input Power Range: -4 to +6 dBm FREQUENCY MULTIPLIERS - SMT v00.0905 • Point-to-Point & VSAT Radios • Test Instrumentation Fo, 3Fo Isolation: >20 dBc @ Fout= 20 GHz 100 KHz SSB Phase Noise: -135 dBc/Hz Single Supply: +5V@ 48 mA • Military & Space RoHS Compliant 3x3 mm SMT Package Functional Diagram General Description The HMC448LC3B is a x2 active broadband frequency multiplier utilizing GaAs PHEMT technology in a leadless RoHS compliant SMT package. When driven by a 0 dBm signal, the multiplier provides +11 dBm typical output power from 22 to 25 GHz. The Fo and 3Fo isolations are >20 dBc up to 22 GHz. This multi-rate frequency multiplier can be used in the generation of a half rate clock for 40 Gbps systems or as part of a multiplier chain to generate a full rate 40 Gbps clock. The HMC448LC3B 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. The HMC448LC3B eliminates the need for wire bonding, allowing the use of surface mount manufacturing techniques. Electrical Specifications, TA = +25° C, Vdd = +5V, 0 dBm Drive Level Parameter Min.
