Product details
Overview
AD8364ACPZ-REEL7 from Analog Devices is a dual-channel, true RMS RF power detector IC operating from LF to 2.7 GHz with ±1 dB dynamic range over 60 dB, 50 mV/dB logarithmic slope, and integrated temperature sensor. It delivers independent linear-in-dB outputs (OUTA/OUTB) and differential channel-difference outputs (OUTP/OUTN), enabling precise RF power monitoring in wireless infrastructure transceivers.
For engineers reviewing the AD8364ACPZ-REEL7 datasheet, AD8364ACPZ-REEL7 pinout, AD8364ACPZ-REEL7 application, or AD8364ACPZ-REEL7 equivalent, this page provides verified technical context, real-world measurement performance across frequency bands (450 MHz–2.5 GHz), confirmed pin functions, and validated alternatives for VSWR monitoring, TSSI, and PA linearization designs.
Technical Context
The AD8364ACPZ-REEL7 integrates two matched TruPwr™ detector cores derived from the AD8362 architecture, enhanced for improved temperature stability and reduced log conformance ripple. Each channel features differential RF inputs (INHA/INLA, INHB/INLB), on-chip op amps for OUTA/OUTB, and dedicated differencing amplifiers driving OUTP/OUTN.
It supports both measurement mode (RMS output scaling) and controller mode (closed-loop gain control), with configurable setpoint inputs (VSTA/VSTB), temperature compensation (ADJA/ADJB), and VLVL-referenced differential output common-mode level. Operation is specified from –40°C to +85°C on a single 5 V supply drawing 70 mA quiescent current.

Applications
| Wireless Infrastructure PA Linearization | Antenna VSWR Monitoring |
|---|---|

Use Scenario: Dual-channel RF power sampling at antenna feed point to compute reflection coefficient magnitude and phase. IC Role / Device Role / Timing Role: AD8364ACPZ-REEL7 acts as embedded VSWR engine - one channel monitors forward path, the other reflected path. Use Value: Achieves <±0.3 dB channel matching over temperature, eliminating need for periodic recalibration in outdoor base stations. |
| Transmitter Signal Strength Indication (TSSI) | Dual-Channel Wireless Radios |
Use Scenario: Reporting instantaneous transmit power to baseband processor for regulatory compliance and adaptive power control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5511ACPZ-R7 | Single-channel, 1 MHz–4 GHz, 45 dB dynamic range, no integrated temperature sensor or difference output | Suitable for cost-sensitive single-path TSSI but lacks VSWR capability and dual-channel correlation | Select when only one RF path requires monitoring and board space is constrained |
| LT5537EDDB#TRPBF | Single-channel, DC–1 GHz, 65 dB range, 25 mV/dB slope, no differential output or temperature sensor | Optimized for lower-frequency ISM bands; requires external op-amp for difference computation | Prefer for sub-1 GHz industrial radios where temperature stability is less critical |
Compared with AD8364ACPZ-REEL7, ADL5511ACPZ-R7 offers wider bandwidth but sacrifices dual-channel correlation and on-chip VSWR computation, while LT5537EDDB#TRPBF provides higher dynamic range at lower frequencies but lacks integrated thermal compensation and differential outputs essential for precision infrastructure monitoring.

FAQ
What is the maximum RF input frequency supported by the AD8364ACPZ-REEL7?
The AD8364ACPZ-REEL7 is fully specified from LF to 2.7 GHz. Performance data is validated at key cellular bands including 450 MHz, 880 MHz, 1880 MHz, 2.14 GHz, and 2.5 GHz. At 2.5 GHz, it maintains ±1 dB dynamic range of 58 dB (Channel A) and 55 dB (Channel B) under typical conditions, confirming operational integrity across the full rated band.
How does the AD8364ACPZ-REEL7 achieve temperature-stable RMS measurements?
The AD8364ACPZ-REEL7 achieves temperature stability through three integrated mechanisms: (1) on-chip matched detector cores with inherent process tracking, (2) a dedicated 2 mV/°C temperature sensor (TEMP pin) for external compensation, and (3) adjustable ADJA/ADJB pins accepting external bias voltages to actively correct gain drift. At 450 MHz, deviation from 25°C output remains within ±0.4 dB over −40°C to +85°C.
Can the AD8364ACPZ-REEL7 measure VSWR directly?
The AD8364ACPZ-REEL7 does not compute VSWR internally, but provides the essential analog building blocks: simultaneous forward and reflected power measurement via its dual channels, plus a differential output (OUTP/OUTN) that directly yields the power ratio required for VSWR calculation. With proper calibration and external computation, it enables highly accurate VSWR monitoring with <±0.3 dB channel matching stability over temperature.
What is the role of the VLVL pin on the AD8364ACPZ-REEL7?
The VLVL pin sets the common-mode voltage level for the differential channel-difference outputs OUTP and OUTN. When connected to VREF (2.5 V) or a voltage divider, it offsets OUTP/OUTN above ground - enabling single-supply operation of downstream ADCs or comparators. The specification requires VLVL + (OUTA/2) ≤ VPSA − 1.31 V to avoid saturation.
Does the AD8364ACPZ-REEL7 require external baluns for RF input?
Yes - the AD8364ACPZ-REEL7 RF inputs (INHA/INLA and INHB/INLB) are differential. For single-ended RF sources, a broadband balun is mandatory. Recommended baluns include Macom ETK4-2T (450 MHz), Mini-Circuits JTX-4-10T (880 MHz), and Murata LDB212G1020C-001 (2.14 GHz). Input return loss degrades to −10 dB without proper balun matching.
