The HMC369LP3 & HMC369LP3E are active miniature x2 frequency multipliers utilizing InGaP GaAs HBT technology in 3x3 mm leadless QFN surface mount packages. 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 & HMC369LP3E are ideal for use in LO multiplier chains allowing reduced parts count versus traditional approaches. The HMC369LP3 & HMC369LP3E are 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.
