The HMC369LP3 is an active miniature x2 frequency multiplier utilizing InGaP GaAs HBT technology in a 3 mm x 3 mm leadless QFN surface mount package. Power output is +4 dBm typical from a single +5.0V supply and varies little vs. input power, temperature and supply voltage. Suppression of undesired fundamental and sub-harmonics is 30 dBc typical with respect to output signal level. The low additive SSB phase noise of -142 dBc/Hz at 100 kHz offset helps the user maintain good system noise performance. The HMC369LP3 is ideal for use in LO multiplier chains allowing reduced parts count versus traditional approaches. The HMC369LP3 is also useful for OC-192 clock recovery. The application of 10 GBPS data to the input generates a -7 dBm clock tone at the output with spurious signals suppressed by 25 dB.
