Analog Devices Inc. ADF5002BCPZ-RL7

Overview

ADF5002BCPZ-RL7 from Analog Devices is a high-frequency divide-by-8 RF prescaler IC designed for microwave PLL frequency extension in 4 GHz to 18 GHz signal chains. It delivers −153 dBc/Hz phase noise at 100 kHz offset (f_IN = 12 GHz), operates from a single 3.3 V supply, draws 30 mA active current, and features differential 100 Ω RF outputs for direct interface with ADF4156/ADF4106 PLLs in point-to-point radio systems.

For engineers reviewing the ADF5002BCPZ-RL7 datasheet, ADF5002BCPZ-RL7 pinout, ADF5002BCPZ-RL7 application, or ADF5002BCPZ-RL7 equivalent, key selection criteria include its 18 GHz max input frequency, integrated RF decoupling, −10 dBm to +10 dBm input sensitivity range, power-down mode (7 mA), and LFCSP package compatibility with high-density RF layouts.

Technical Context

The ADF5002BCPZ-RL7 implements a fixed divide-by-8 architecture using high-speed SiGe bipolar technology optimized for broadband RF division without external biasing. Its dual supply rails (VDD1 for input/divider, VDD2 for output stage) enable independent optimization of input sensitivity and output drive strength across the full 4–18 GHz band.

It supports both single-ended (50 Ω load) and differential (100 Ω differential load) output configurations, with internal 1 pF AC-coupling capacitors on each RFOUT pin and integrated 100 Ω load resistors tied to VDD2 - eliminating need for external termination in standard PLL interfacing.

FAQ

What is the maximum RF input frequency supported by the ADF5002BCPZ-RL7?

The ADF5002BCPZ-RL7 supports RF input frequencies from 4 GHz up to 18 GHz, as specified in its absolute maximum ratings and confirmed in Table 1 of the Rev. 0 datasheet. This upper limit is validated across the full −40°C to +105°C operating temperature range and applies to both single-ended and differential input configurations. The ADF5002BCPZ-RL7 maintains −10 dBm to +10 dBm input sensitivity throughout this band, enabling direct interface with Ka-band VCOs without external conditioning.

Does the ADF5002BCPZ-RL7 require external decoupling capacitors?

The ADF5002BCPZ-RL7 integrates RF decoupling capacitors (3 pF on RFIN, 1 pF on each RFOUT), but external supply decoupling remains mandatory: each VDD1 and VDD2 pin requires a parallel 0.1 μF ceramic capacitor with a 10 pF capacitor placed as close as possible to the pin. These external components stabilize supply rails against high-frequency transients and ensure consistent 30 mA active current draw and −153 dBc/Hz phase noise performance across the 4–18 GHz band.

Can the ADF5002BCPZ-RL7 operate with a single 3.3 V supply?

Yes, the ADF5002BCPZ-RL7 is fully compatible with a single 3.3 V supply, as stated in the General Description and Specifications sections. Both VDD1 and VDD2 accept 3.0 V to 3.6 V, and the datasheet confirms typical operation at 3.3 V ±10%. The ADF5002BCPZ-RL7 draws 30 mA total supply current under these conditions and interfaces directly with 3.3 V-compatible PLLs such as the ADF4156, eliminating level-shifting circuitry.

What is the function of the CE pin on the ADF5002BCPZ-RL7?

CE (Pin 7) is the chip enable input for the ADF5002BCPZ-RL7. It is active-high: when CE is high, the device operates normally; when CE is low, it enters power-down mode drawing only 7 mA. The pin features an internal weak pull-up resistor, so it may be left unconnected if power-down functionality is not required. No external pull-up is needed unless faster wake-up timing or noise immunity is critical in the application design involving the ADF5002BCPZ-RL7.

Is the ADF5002BCPZ-RL7 pin-compatible with other devices in the ADF500x family?

The ADF5002BCPZ-RL7 shares the same 16-lead LFCSP_WQ package (CP-16-18) and pin configuration with the ADF5001BCPZ-RL7, including identical GND, RFIN, RFOUT, VDD1, VDD2, and CE placements. However, the ADF5002BCPZ-RL7 implements ÷8 division versus ÷4 in the ADF5001BCPZ-RL7 - meaning they are mechanically and electrically pin-compatible but functionally distinct. System-level validation is required when substituting the ADF5002BCPZ-RL7 for ADF5001BCPZ-RL7 due to the halved output frequency.
