Richardson RFPD, Inc. announced availability and full design support capabilities for a new 18 GHz microwave phase locked loop (PLL) synthesizer from Analog Devices, Inc. (ADI).
The ADF41020 can be used to implement local oscillators as high as 18 GHz in the up-conversion and down-conversion sections of wireless receivers and transmitters. It consists of a low noise, digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and high frequency programmable feedback dividers (A, B, and P). A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). The synthesizer can be used to drive external microwave VCOs via an active loop filter. Its very high bandwidth means a frequency doubler stage can be eliminated, simplifying system architecture and reducing cost. The ADF41020 is ideally-suited for point-to-point, wireless infrastructure and test equipment applications.
Key features of the ADF41020 include:
· 4-18 GHz range
· RF Input Sensitivity as low as -10 dBm
· Programmable prescaler: 8/9, 16/17, 32/33, 64/65
· Programmable charge pump currents
· 2.85 V to 3.15 V PLL power supply
· 3-wire serial interface
· Analog and digital lock detect
· Hardware and software power-down mode
The ADF41020 is part of ADI's Select Products for Q1, 2013.
