Analog Devices Inc. ADL5812ACPZ-R7

Overview

ADL5812ACPZ-R7 from Analog Devices is a dual-channel, high-linearity, passive double-balanced mixer with integrated IF amplifiers and wideband LO amplifiers, operating from 700 MHz to 2800 MHz RF and 250 MHz to 2800 MHz LO. It delivers 6.7 dB power conversion gain, 27.2 dBm input IP3, and 11.6 dB SSB noise figure at 1900 MHz, enabling use in cellular base station diversity receivers and broadband radio link downconverters.

For engineers reviewing the ADL5812ACPZ-R7 datasheet, ADL5812ACPZ-R7 pinout, ADL5812ACPZ-R7 application, or ADL5812ACPZ-R7 equivalent, key selection criteria include its dual-channel architecture, programmable RF baluns, serial port interface control, 40-lead 6 mm × 6 mm LFCSP package, and support for single-ended RF/LO inputs with differential IF outputs.

Technical Context

The ADL5812ACPZ-R7 employs broadband square-wave limiting LO amplifiers-eliminating energy storage elements-to enable high-side or low-side LO injection across its full 250 MHz–2800 MHz range while reducing DC current at lower LO frequencies. Its doubly balanced passive mixer cores provide exceptional LO-to-RF (−46 dBm) and LO-to-IF (−37 dBm) leakage, plus >26 dB RF-to-IF isolation.

Integrated programmable RF baluns optimize performance over 700 MHz–2800 MHz, and two independent logic-controlled power-down modes reduce quiescent current to 1.5 mA per channel. All functions-including VGS programming, LPF tuning, and RFB selection-are managed via a 3-wire SPI interface.

FAQ

What is the operating temperature range of the ADL5812ACPZ-R7?

The ADL5812ACPZ-R7 operates over a −40°C to +85°C ambient temperature range. This specification is validated across all key parameters including conversion gain, input IP3, and noise figure, ensuring reliable performance in outdoor base station enclosures and industrial-grade radio equipment where thermal cycling occurs.

Does the ADL5812ACPZ-R7 require external LO filtering?

Yes-the ADL5812ACPZ-R7 datasheet specifies that LO source filtering is required to achieve the stated 21 dB blocker noise figure. Unfiltered LO sources introduce out-of-band harmonics that degrade SSB noise figure under blocking conditions, particularly near the IF band.

Can the ADL5812ACPZ-R7 operate from a 3.6 V supply?

Yes-the ADL5812ACPZ-R7 supports single-supply operation from 3.6 V to 5.0 V. At 3.6 V, typical supply current drops to ~270 mA (vs. 412 mA at 5 V), with only minor degradation in conversion gain (−0.8 dB) and IP3 (−1.2 dBm) at 1900 MHz, preserving usability in low-voltage systems.

How is RF port return loss tuned on the ADL5812ACPZ-R7?

RF port return loss on the ADL5812ACPZ-R7 is tuned via the 3-wire SPI interface using programmable RF balun settings. The device supports >20 dB broadband return loss across 700–2800 MHz when configured with optimal RFB register values, eliminating manual matching network adjustments.

What is the function of the V1LO1–V1LO4 and V2LO1–V2LO4 pins on the ADL5812ACPZ-R7?

The V1LO1–V1LO4 and V2LO1–V2LO4 pins on the ADL5812ACPZ-R7 are positive supply voltage terminals for the two independent LO amplifier sections. Each set powers one channel's LO driver circuitry and must be decoupled locally to ensure stable square-wave LO generation and minimize supply-induced phase noise.
