When driven with a 0 to +6 dBm input signal, it delivers +14 dBm typical output power with excellent Fo and 3Fo isolation of 15 dBc at 16 GHz. The additive SSB phase noise of -139 dBc\/Hz at 100 kHz offset makes it ideal for low-phase-noise LO chains. Housed in a 16-lead QFN (3 mm x 3 mm) surface-mount package, it eliminates wire bonding and supports standard SMT assembly.","working_principle":"The HMC561LP3ETR utilizes GaAs PHEMT technology to implement an active frequency doubling function. The input RF signal is applied to a nonlinear PHEMT device that generates harmonics of the fundamental frequency. An integrated bandpass filter network extracts the second harmonic (2 x Fin) while suppressing the fundamental (Fo) and third harmonic (3Fo). The active design provides conversion gain rather than loss, delivering +14 dBm output from only +5 dBm input drive. The Vdd supply pin powers the internal amplifier stages, while the Vgg pin allows gate bias adjustment to optimize drain current (Idd) at 98 mA. The AC-coupled RF input and output are internally matched to 50 Ohms, requiring no external matching components.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1, 3, 10, 12<\/td><td>GND<\/td><td>Ground; connect to RF\/DC ground plane<\/td><\/tr><tr><td>2<\/td><td>RFIN<\/td><td>RF input; AC coupled and matched to 50 Ohms, 4-10.5 GHz<\/td><\/tr><tr><td>4-9, 14, 16<\/td><td>N\/C<\/td><td>No connect; specified with pins connected to RF\/DC ground<\/td><\/tr><tr><td>11<\/td><td>RFOUT<\/td><td>RF output; AC coupled and matched to 50 Ohms, 8-21 GHz<\/td><\/tr><tr><td>13<\/td><td>Vdd<\/td><td>Supply voltage +5V +\/-0.5V; requires 100pF, 1000pF, and 2.2uF bypass caps<\/td><\/tr><tr><td>15<\/td><td>Vgg<\/td><td>Gate control for multiplier; adjust for Idd = 98 mA<\/td><\/tr><\/table>","application_scenarios":"<ul><li><strong>LO Multiplier Chains<\/strong>: Point-to-point and VSAT radio transceivers requiring frequency doubling with high output power<\/li><li><strong>Clock Generation<\/strong>: SONET OC-192 and SDH STM-64 high-speed clock synthesis<\/li><li><strong>Test Instrumentation<\/strong>: Signal source generation for microwave test equipment and synthesizers<\/li><li><strong>Military and Space<\/strong>: Radar and electronic warfare systems requiring robust, low-phase-noise frequency conversion<\/li><li><strong>Satellite Communications<\/strong>: Ka-band upconverter LO chain generation from lower-frequency references<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Function<\/th><th>Fout<\/th><th>Pout<\/th><th>Package<\/th><\/tr><tr><td>HMC560LP3E<\/td><td>Analog Devices<\/td><td>x2 Multiplier<\/td><td>7-14 GHz<\/td><td>+13 dBm<\/td><td>QFN-16<\/td><\/tr><tr><td>HMC562LC5<\/td><td>Analog Devices<\/td><td>x2 Multiplier<\/td><td>16-28 GHz<\/td><td>+12 dBm<\/td><td>LC5<\/td><\/tr><tr><td>HMC-XDB110<\/td><td>Analog Devices<\/td><td>x2 Multiplier<\/td><td>20-40 GHz<\/td><td>+11 dBm<\/td><td>Bare Die<\/td><\/tr><tr><td>AMMP-6132<\/td><td>Macom<\/td><td>x2 Multiplier<\/td><td>14-27 GHz<\/td><td>+10 dBm<\/td><td>PQFN<\/td><\/tr><tr><td>MK-2+<\/td><td>Mini-Circuits<\/td><td>x2 Multiplier<\/td><td>5-1200 MHz<\/td><td>+4 dBm<\/td><td>SMA<\/td><\/tr><\/table>\n<p>HMC561LP3ETR is an x2 active multiplier from ADI\/Hittite in 3x3mm QFN-16 covering 8-21GHz output.
