Analog Devices Inc. ADRV9026BBCZ

Overview

ADRV9026BBCZ from Analog Devices is a highly integrated quad RF transceiver with dual observation receivers, supporting 75 MHz–6000 MHz center frequency, 200 MHz receiver bandwidth, 200 MHz transmitter large-signal bandwidth, 450 MHz observation bandwidth, and 24.33 Gbps JESD204B/C interface - deployed in 5G massive MIMO base station radios for real-time closed-loop transmit calibration.

For engineers reviewing the ADRV9026BBCZ datasheet, ADRV9026BBCZ pinout, ADRV9026BBCZ application, or ADRV9026BBCZ equivalent, this page delivers verified RF performance specs, multichip synchronization capability, LO phase noise behavior across bands, observation path calibration architecture, and power supply sequencing requirements critical for cellular infrastructure design.

Technical Context

The ADRV9026BBCZ implements five fully integrated fractional-N PLLs: two for Tx/Rx signal paths (low-noise, low-power), one dedicated LO for observation receivers, one for converter/digital clocks, and one for the JESD204B/C serial interface. All VCOs and loop filter components are on-die and digitally tunable via SPI.

Its direct-conversion architecture includes four independent transmitters with QEC, DC offset correction, and programmable FIR filtering; four wide-dynamic-range receivers with 30 dB analog gain range; and two time-shared observation receivers (two inputs each) supporting up to 450 MHz instantaneous bandwidth - all synchronized via multichip phase alignment of LOs and baseband clocks.

Key Specifications

Pinout & Package

FAQ

What is the maximum observation receiver bandwidth supported by the ADRV9026BBCZ?

The ADRV9026BBCZ supports a maximum observation receiver bandwidth of 450 MHz. This is validated across all operating frequencies from 75 MHz to 6000 MHz and enables capture of wideband PA distortion for digital predistortion (DPD) modeling. The device achieves −64 dB SFDR in this mode with PHIGH − 8 dB input, and uses programmable FIR filtering to maintain <0.1 dB gain flatness over any 20 MHz span within the 450 MHz band.

Does the ADRV9026BBCZ support both FDD and TDD operation?

Yes, the ADRV9026BBCZ explicitly supports both FDD and TDD applications as stated in its General Description and Features sections. Its four independent transmitters and receivers can be configured with separate LOs and timing controls, and the observation receivers operate time-shared to monitor individual PA outputs regardless of duplex mode. The device's multichip synchronization ensures phase coherence across all channels in either configuration.

How many integrated PLLs does the ADRV9026BBCZ contain, and what are their roles?

The ADRV9026BBCZ contains five fully integrated fractional-N PLLs. Two serve the main transmitter and receiver signal paths; one supports the observation receiver LO; one generates clocks for ADCs, DACs, and digital circuits; and one supplies the JESD204B/C serial interface clock. All VCOs and loop filter components are on-die and adjustable via SPI, eliminating external synthesizer components.

What is the RF input impedance of the ADRV9026BBCZ receivers and observation receivers?

The ADRV9026BBCZ receivers and observation receivers have a nominal differential input impedance of 100 Ω, as specified in Tables 1 and 2 of the Rev. C datasheet. This is consistent across all four Rx channels and both ORx paths (ORX1/ORX2 and ORX3/ORX4). Input port return loss exceeds 10 dB, and maximum source VSWR is rated at 3:1 - enabling direct interface with standard baluns without additional matching networks.

Can the ADRV9026BBCZ operate without external LO sources?

Yes, the ADRV9026BBCZ operates without external LO sources. Its five on-chip fractional-N PLLs generate all required local oscillator signals - including those for transmitters, receivers, observation receivers, converters, and the JESD204B/C interface. External references (e.g., 30.72 MHz or 122.88 MHz) are required for PLL locking, but no off-chip VCOs, synthesizers, or LO distribution circuitry are needed for full RF functionality.
