Analog Devices Inc. EVAL-AD607EBZ

Overview

EVAL-AD607EBZ from Analog Devices is an evaluation board for the AD607 3 V low-power receiver IF subsystem IC, integrating mixer, IF amplifiers, I/Q demodulator, and PLL-based quadrature oscillator. It supports IF frequencies from 400 kHz to 12 MHz, delivers 90 dB gain control range, −15 dBm mixer 1 dB compression, and enables GSM/TETRA/satellite terminal receiver prototyping with <25 mW power consumption.

For engineers reviewing the EVAL-AD607EBZ datasheet, EVAL-AD607EBZ pinout, EVAL-AD607EBZ application, or EVAL-AD607EBZ equivalent, this board provides full access to all AD607 signals-including RFHI/RFLO, LOIP, IFHI/IFLO, DMIP, IOUT/QOUT, FLTR, and PRUP-for RF front-end characterization, AGC loop validation, quadrature demodulation testing, and baseband converter interface verification with AD7013/AD7015.

Technical Context

The EVAL-AD607EBZ implements the complete signal chain of the AD607 IC: a doubly balanced Gilbert-cell mixer (500 MHz RF/LO bandwidth), four-stage linear-in-dB IF amplifier (45 MHz bandwidth, ±560 mV output), and I/Q demodulators driven by an on-chip phase-locked quadrature VCO (0.4–12 MHz range). All biasing, power-down (CMOS-compatible PRUP), and gain control (GAIN/GREF) interfaces are brought out to test points and connectors.

It supports direct connection to RF sources (via SMA), IF spectrum analyzers (IFOP), baseband oscilloscopes (IOUT/QOUT), and external PLL reference inputs (FDIN), with on-board passive filtering (R/C networks at FLTR, IFOP, DMIP) and mid-supply generation (VMID = VPOS/2) matching AD607's internal architecture and DC operating conditions.

FAQ

What is the primary function of the EVAL-AD607EBZ evaluation board?

The EVAL-AD607EBZ is a fully assembled and tested evaluation platform for the AD607 receiver IF subsystem IC. It enables engineers to characterize mixer linearity, validate IF amplifier gain control, verify I/Q demodulator quadrature accuracy, and interface with baseband converters like the AD7015 - all using the exact signal routing, biasing, and filtering specified in the AD607 datasheet. The board directly implements the AD607's functional block diagram with accessible test points and SMA connectors.

Does the EVAL-AD607EBZ support both manual and automatic gain control (AGC) testing?

Yes, the EVAL-AD607EBZ supports both modes. The GAIN and GREF headers allow precise DC voltage injection (0–2.2 V) to emulate manual gain control or external AGC detector output. The board also includes provisions to connect an external DAC or op-amp-based AGC loop, and its layout preserves AD607's 20 mV/dB gain scaling and temperature-compensated control interface as defined in the datasheet.

Can the EVAL-AD607EBZ be used to evaluate AM, SSB, and CW demodulation capabilities of the AD607?

Yes. The EVAL-AD607EBZ exposes FDIN, FLTR, and DMIP pins required to configure the AD607's PLL for external beat-frequency oscillator (BFO) locking - enabling synchronous product detection for AM, CW, and SSB reception. Its test points allow injection of BFO signals and measurement of IOUT/QOUT baseband outputs under these modulation schemes, as validated in Analog Devices' application notes and TPC 9–12.

What RF and IF signal interfaces does the EVAL-AD607EBZ provide?

The EVAL-AD607EBZ features SMA connectors for RF input (RFHI/RFLO), LO input (LOIP), IF output (IFOP), and baseband I/Q outputs (IOUT/QOUT). All critical AD607 pins - including VMID, PRUP, GAIN, GREF, DMIP, FDIN, and FLTR - are accessible via solder pads or headers. The board maintains 50 Ω impedance on RF paths and uses AC-coupling consistent with AD607's ±56 mV RF input and ±150 mV DMIP input limits.

Is the EVAL-AD607EBZ compatible with the AD7015 GSM baseband converter?

Yes, the EVAL-AD607EBZ is explicitly designed for interoperability with the AD7015. Its IOUT and QOUT outputs deliver ±1.23 V full-scale AC-coupled signals matching the AD7015's RX ADC input requirements, and its GREF header supports connection to the AD7015's REFOUT (1.23 V) to achieve 16.4 mV/dB gain scaling - enabling accurate RSSI reporting without external references, as documented in Figure 18 of the AD607 datasheet.
