The ADF4106 frequency synthesizer can be used to implement local oscillators 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, programmable A counter and B counter, and a dual-modulus prescaler (P/P + 1). The A (6-bit) counter and B (13-bit) counter, in conjunction with the dual-modulus prescaler (P/P + 1), implement an N divider (N = BP + A). In addition, the 14-bit reference counter (R Counter) allows selectable REFIN frequencies at the PFD input. A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). Its very high bandwidth means that frequency doublers can be eliminated in many high frequency systems, simplifying system architecture and reducing cost.ADF4106-EP Supports defense and aerospace applications (AQEC standard).Applications Broadband wireless access Satellite systems Instrumentation Wireless LANS Base stations for wireless radios

The phase frequency detector (PFD) operates up to 250 MHz (integer N mode)/125 MHz (fractional-N mode) for improved phase noise and spur performance. The variable modulus, ?-? modulator allows extremely fine resolution when using a 49-bit divide value. The ADF41513 can be used as an integer N phase-locked loop (PLL), or it can be used as a fractional-N PLL with either a fixed modulus for subhertz frequency resolution or variable modulus for subhertz exact frequency resolution.A complete PLL is implemented when the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO). The 26.5 GHz bandwidth eliminates the need for a frequency doubler or divider stage, simplifying system architecture and reducing cost.
