The HMC494LP3 is a low noise Divide-by-8 Static Divider utilizing InGaP GaAs HBT technology packaged in a leadless 3x3 mm QFN surface mount plastic package. This device operates from DC (with a square wave input) to 18 GHz input frequency from a single +5.0V DC supply. The low additive SSB phase noise of -150 dBc/Hz at 100 kHz offset helps the user maintain excellent system noise performance.
The HMC494LP3 is a GaAs HBT MMIC that provides a divide‑by‑8 function from DC (square‑wave input) up to 18 GHz. It features ultra‑low SSB phase noise of –150 dBc/Hz at 100 kHz offset, a compact 3 × 3 mm QFN package, and requires only a single +5 V supply.
Typical applications include point‑to‑point and multi‑point radios, VSAT, fiber‑optic test equipment, and military systems. The datasheet includes electrical specifications, pin descriptions, evaluation PCB guidelines, and an application circuit.
