7 GHz PLL synthesizer for microwave LO generation
The ADF4107BRUZ is a PLL-based frequency synthesizer (RF type) from Analog Devices, rated for a maximum input frequency of 7 GHz. That 7 GHz ceiling puts it squarely in the C-band and upper S-band — think satellite downconverters, point-to-point microwave links, and 5G mmWave test heads where the LO needs to reach into the 6-7 GHz range without a multiplier stage.
Supply rail and temperature grade
Operates from a single 2.7V to 3.3V rail — a common 3.3V supply is fine, but the lower end matters if you are sharing a 2.8V LDO with a baseband ASIC.
Package and footprint considerations
Housed in a 16-TSSOP package (0.173", 4.40 mm width), surface-mount only. The 0.65 mm pitch is layout-friendly — a 2-layer board can route the supply and loop-filter components without vias. The supplier device package is 16-TSSOP; no exposed pad, so thermal relief is through the leads only. Keep the analog and digital supply traces separated to avoid pulling the VCO control line.
Sourcing and lifecycle posture
For volume requirements or urgent BOM fills, this part is sourced to order per RFQ — current pricing and lead time confirmed at quote time.
