Low Phase Noise 2-30GHz SMT Amplifiers Optimized for Marki Mixers

Concerned about additive phase noise? Looking to eliminate negative supply rails and power sequencing? Is board space a premium? Introducing Marki Microwave’s first low phase noise, positive-bias, no bias tee required, surface mount LO driver amplifiers featuring a wide 2 to 30GHz bandwidth! The APM-6848SM, a dual-stage design with 22dB of small-signal gain, provides a +20dBm typical saturated output power with an input power of only 0 to 5dBm. This is ideal for driving our L, H, and S-diode mixers directly from your VCO or synthesizer output. Also available is our new APM-6849SM, a single-stage design with 11dB of gain and +21dBm saturated output, and an impressive -170dBc/Hz phase noise at 10kHz offset. Careful consideration was made to power consumption, with APM-6848SM drawing only 47mA at 5V and APM-6849SM drawing just 23mA, making these some of the most power efficient wideband low phase noise amplifiers on the market. Both amplifiers are available in surface-mount QFN packages and connectorized evaluation modules.
