Analog Devices Inc. ADL5365ACPZ-R7

Overview

ADL5365ACPZ-R7 from Analog Devices is a high-linearity, single-ended-input balanced passive mixer IC with integrated RF balun and dual-path LO switch, operating from 1200 MHz to 2500 MHz RF input, delivering 7.3 dB power conversion loss, 36 dBm input IP3, and 8.3 dB SSB noise figure at 5 V supply. It enables low-side or high-side LO injection in cellular base station receivers and transmit observation paths.

For engineers reviewing the ADL5365ACPZ-R7 datasheet, ADL5365ACPZ-R7 pinout, ADL5365ACPZ-R7 application, or ADL5365ACPZ-R7 equivalent, key selection criteria include RF/LO frequency coverage (1200–2500 MHz), differential IF output capability, LO switch isolation (>40 dB), power-down functionality (<200 µA), and 5 mm × 5 mm LFCSP thermal performance.

Technical Context

The ADL5365ACPZ-R7 integrates a doubly balanced passive MOSFET mixer core with on-die RF balun and SPDT LO switch, enabling single-ended 50 Ω RF and LO interfaces while maintaining >−30 dBm LO-to-RF leakage and −50 dBc RF-to-IF isolation. Its BiCMOS process supports simultaneous high IIP3 (36 dBm) and low noise figure (8.3 dB) across temperature.

LO subsystem includes a three-stage limiting amplifier and resistor-programmable current control (95 mA at 5 V, 56 mA at 3.3 V), with dedicated VGS0/VGS1 pins for mixer bias tuning and PWDN logic control for sub-200 µA shutdown-valid only under ≤3.6 V operation per datasheet specification.

Key Specifications

Pinout & Package

The ADL5365ACPZ-R7 is housed in a 5 mm × 5 mm, 20-lead LFCSP package with exposed paddle soldered to ground for thermal and EMI performance. Pin 1 (VPMX) is the main positive supply; Pins 18–19 (IFOP/IFON) deliver differential IF output; Pins 11–12 (LOI1/LOI2) accept ac-coupled LO inputs; Pin 17 (PWDN) controls power-down mode.

FAQ

What is the recommended LO drive level for optimal performance of the ADL5365ACPZ-R7?

The ADL5365ACPZ-R7 achieves specified performance-including 7.3 dB conversion loss and 36 dBm IIP3-at a nominal LO drive of 0 dBm. Operation down to −6 dBm increases conversion loss by ~0.7 dB; exceeding +10 dBm risks degradation and is outside absolute maximum ratings. The integrated LO amplifier ensures consistent drive level regardless of input variation.

Can the ADL5365ACPZ-R7 operate with a 3.3 V supply, and how does performance change?

Yes, the ADL5365ACPZ-R7 supports 3.3 V operation with reduced quiescent current (56 mA vs. 95 mA at 5 V). Key trade-offs include slightly higher conversion loss (7.4 dB vs. 7.3 dB), lower IIP3 (32 dBm vs. 36 dBm), and unchanged noise figure (8.4 dB). Power-down mode remains functional only below 3.6 V.

What is the function of the VGS0 and VGS1 pins on the ADL5365ACPZ-R7?

VGS0 and VGS1 are mixer gate bias control inputs that adjust the transconductance of the passive MOSFET mixer core. Grounding both sets nominal bias; applying logic-high levels tunes linearity versus noise trade-offs. Their use enables optimization for specific RF channel loading conditions without changing external circuitry.

Is the ADL5365ACPZ-R7 suitable for upconversion applications?

Yes, the ADL5365ACPZ-R7 is bidirectional and fully characterized for upconversion. At 5 V, it delivers 7.5 dB conversion loss and 33 dBm IIP3 when translating 153 MHz IF to 1900 MHz RF with 1697 MHz LO. Performance metrics remain within datasheet limits across the full RF band.

How should the exposed paddle (EPAD) of the ADL5365ACPZ-R7 be handled in PCB layout?

The exposed paddle must be soldered directly to a solid ground plane using ≥9 thermal vias (3×3 array) to achieve the specified θJB = 14.74°C/W. Inadequate grounding causes junction temperature rise, degrading noise figure and accelerating long-term reliability failure-especially under continuous 5 V/95 mA operation.
