The ADF4368 is a high performance, ultralow jitter, integer-N and fractional-N phase-locked loop (PLL) with integrated VCO ideally suited for frequency conversion applications.The high performance PLL has a figure of merit of -239dBc/Hz, very low 1/f Noise of normalized -287dBc/Hz and high PFD frequency that can achieve ultralow in-band noise and integrated jitter. The ADF4368 can generate any frequency from 800 MHz to 12.8 GHz without an internal doubler, thereby eliminating the need for sub-harmonic filters. Σ-Δ modulator includes a 25-bit fixed modulus which allows hertz frequency resolution and an additional 24-bit variable modulus which allows even finer resolution and flexibility for frequency planning. 9 dBm output power at 12.8 GHz in single ended configuration with 16 step power adjust feature makes it very useful for any application.For multiple frequency conversion applications such as phase array radar or massive MIMO systems, the outputs of multiple ADF4368 can be aligned by using SYNC input or EZSync. EZSync method is used when it is difficult to distribute the SYNC signal to all parts precisely. For applications that require deterministic delay or delay adjustment capability, a programmable reference to output delay with The simplicity of the ADF4368 block diagram eases development time with a simplified SPI register map, external SYNC input and repeatable multi-chip phase alignment both in integer and fractional mode.APPLICATIONSWireless infrastructure (MC-GSM, 5G)Test and MeasurementAerospace and Defense

The ADF41020 frequency synthesizer 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 software-compatible with the existing ADF4106/ADF4107/ADF4108 family of devices from Analog Devices, Inc. Their pinouts match very closely with the exception of the ADF41020’s single-ended RF input pin, meaning only a minor layout change is required when updating current designs.Applications Microwave point-to-point/multipoint radios Wireless infrastructure VSAT radios Test equipment Instrumentation
