What are the key features of ADF4118BRUZ?
- RF PLL frequency synthesizer supporting output frequencies up to 3 GHz for cellular base station and wireless LAN local oscillator designs
- 16-pin TSSOP package with 3-wire SPI interface enabling easy integration with microcontrollers and DSP systems in space-constrained PCB layouts
- Low phase noise PLL architecture with programmable R and N counters enabling flexible channel spacing from kHz to MHz steps
What is ADF4118BRUZ used for?
ADF4118BRUZ is used in cellular base station transceivers, point-to-point microwave radio links, and test-and-measurement signal generators requiring stable local oscillator frequencies up to 3 GHz. Its programmable integer-N PLL architecture allows channel-spaced frequency synthesis with low phase noise, making it suitable for WCDMA, GSM, and ISM band radio designs. The compact 16-pin TSSOP footprint and 3-wire SPI control interface simplify integration into multi-channel RF front-end modules.

Frequently Asked Questions
Up to what output frequency can ADF4118BRUZ synthesize, and which wireless bands does that cover?
ADF4118BRUZ synthesizes frequencies up to 3 GHz, covering 800 MHz cellular, 1.9 GHz PCS, 2.1 GHz WCDMA, and 2.4 GHz ISM bands. Its programmable R and N counters allow channel spacing as fine as a few kHz, making it suitable as a local oscillator for GSM, WCDMA, and Bluetooth 2.4 GHz transceiver designs.
How is ADF4118BRUZ configured in a system, and what interface does it require from a host microcontroller?
ADF4118BRUZ uses a 3-wire SPI-compatible serial interface operating at 3.3 V logic levels, requiring only CLK, DATA, and LE lines from the host MCU. Frequency programming is done by writing 21-bit words to the R counter and N counter registers, with lock detect output available as a digital status pin indicating PLL lock within the programmed loop bandwidth.
For a 2.1 GHz WCDMA radio design, when should ADF4118BRUZ be considered over a fractional-N synthesizer?
ADF4118BRUZ is an integer-N synthesizer suitable when channel spacing equals the reference frequency divided by the R counter, typically 200 kHz for GSM or 5 MHz for WCDMA channels. It offers simpler spurious performance versus fractional-N designs, and its 16-pin TSSOP package fits standard RF PCB footprints with a 0.65 mm pin pitch, making it a cost-effective choice when sub-channel resolution is not required.
