Hittite announces a family of InGaP HBT MMIC prescalers which operate from DC (with a square wave input) to 18 GHz. The low additive SSB Phase Noise, -151 dBc/Hz at 100 kHz offset, make this family of dividers suited for commercial PLL applications such as VSAT, point to point radio, fiber optic, and test equipment markets, as well as military PLL systems. The HMC492LP3, HMC493LP3, and the HMC494LP3 offer divide ratios of 2, 4, and 8 respectively, and are housed in 3 × 3mm 16 lead (LP3) QFN surface mount packages sharing a common pin assignment. Each of these dividers operate from a single +5 V supply, and accept a input power range of 㪧 dBm to +10 dBm at midband.
