The ADL5802 uses high linearity, double-balanced, active mixer cores with integrated LO buffer amplifiers to provide high dynamic range frequency conversion from 100 MHz to 6 GHz. The mixers benefit from a proprietary linearization architecture that provides enhanced input IP3 performance when subject to high input levels.

The ADL5960 is a wideband vector network analyzer front-end consisting of a resistive bidirectional bridge, down-conversion mixers, programmable IF amplifiers and filters, and a highly flexible local oscillator (LO) interface. The bridge provides >10 dB of directivity up to 17 GHz, and the primary transmission line of the bridge, from RFIN to RFOUT, is wideband impedance matched to 50 ? and has a flat frequency response with The ADL5960 supports several different LO interface configurations that simplify the clocking design of a VNA solution as well as the interfacing of the device to an analog-to-digital converter (ADC). The frequency divider and multipliers in the LO interface enable measurement sweeps beyond the operating frequency range of the source driving the (LOP and LOM) pins. This enables operation over the full 20 GHz bandwidth of the ADL5960 using a 6 GHz synthesizer as the LO source. The IF frequency offset mixer, driven through the (OFP and OFM) interface, enables further simplification by allowing the (swept) RF and LO signals to be driven by the same frequency source. The frequency of the IF output signals is then determined by the low-frequency source driving the (OFP and OFM) interface. Driving this interface at the ADC sample frequency with the divide by 4 enabled, automatically centers the IF output signal in the first Nyquist zone.The IF filters with programmable bandwidth and IF amplifiers with individually programmable gain enable simultaneous dynamic range optimization of the IF signals at the incident channel (IFFP and IFFM) and reverse channel (IFRP and IFRM) IF interfaces. The IF amplifiers have an adjustable output common-mode level and sufficient drive capability to interface directly with a wide range of ADCs.All configurations and functions in the ADL5960 are fully programmable through a 3-wire serial peripheral interface (SPI) using the ADI-SPI interface standard.
