Analog Devices Inc. ADRF5347BCCZN-RL

Overview

ADRF5347BCCZN-RL from Analog Devices is a high-linearity, reflective silicon SP4T RF switch designed for 1 GHz to 6 GHz signal routing in phased-array and beamforming systems. It delivers 0.42 dB typical insertion loss up to 3.8 GHz, +84 dBm typical input IP3, 39 dBm CW power handling at 105°C case temperature, and LVCMOS/LVTTL-compatible 3-pin control (V1/V2/LS). It enables back-to-back phase shifter architectures in 5G base station antenna modules.

For engineers reviewing the ADRF5347BCCZN-RL datasheet, ADRF5347BCCZN-RL pinout, ADRF5347BCCZN-RL application, or ADRF5347BCCZN-RL equivalent, key selection criteria include its 20-terminal LGA package thermal performance, 720 ns 0.1 dB settling time, bidirectional RF path capability, and support for LTE signal peak power up to 49 dBm with 10 dB PAR.

Technical Context

The ADRF5347BCCZN-RL integrates an internal driver enabling simplified 3-pin logic control (LS/V1/V2) with eight defined states per Table 6, supporting both low- and high-logic polarity configurations. Its reflective architecture allows bidirectional operation without DC blocking when RF line potential is 0 V, and all ports are internally 50 Ω matched.

It operates from −40°C to +105°C with dual supplies: +5.0 V (VDD, 2.4 mA typical) and −3.4 V (VSS, 0.4 mA typical). Timing is governed by tPROG (10 ns min), tHOLD (20 ns min), and tDEAD (1.3–2 μs), ensuring robust state transitions under fast control updates in TDD systems.

FAQ

What is the maximum RF input power the ADRF5347BCCZN-RL can handle continuously at 105°C case temperature?

The ADRF5347BCCZN-RL supports 39 dBm continuous wave (CW) RF input power at TCASE = 105°C for long-term (>10 years) operation. This rating applies to through power with proper thermal management via the EPAD and PCB ground plane. For LTE signals with 10 dB peak-to-average ratio (PAR), it handles 39 dBm average and 49 dBm peak power under the same thermal condition.

Does the ADRF5347BCCZN-RL require external DC blocking capacitors on its RF ports?

No, the ADRF5347BCCZN-RL does not require external DC blocking capacitors on RFC, RF1–RF4 when the RF line potential is 0 V, because all RF ports are DC-coupled and internally matched to 50 Ω. However, if the RF signal path has non-zero DC bias, DC blocking capacitors must be added to prevent damage or performance degradation.

How many control pins does the ADRF5347BCCZN-RL use, and what logic levels are supported?

The ADRF5347BCCZN-RL uses three digital control pins: V1, V2, and LS. It supports LVCMOS- and LVTTL-compatible logic levels with VIH = 1.07–3.45 V and VIL = 0–0.7 V. The LS pin selects logic polarity, enabling eight distinct SP4T states via the truth table in the datasheet.

Can the ADRF5347BCCZN-RL be used in back-to-back configuration for phase shifting?

Yes, the ADRF5347BCCZN-RL is explicitly designed for back-to-back phase shifter implementations. Two devices can be configured with inverted LS control to achieve precise 0°, 30°, 60°, and 90° phase steps at 3.6 GHz, as validated in Analog Devices' reference design (Figure 31–34).

What is the thermal resistance (θJC) of the ADRF5347BCCZN-RL package?

The ADRF5347BCCZN-RL has a junction-to-case (θJC) thermal resistance of 37°C/W, measured from channel to package bottom under simulated conditions with the EPAD held at 105°C. This value assumes optimal PCB thermal design with multiple vias connecting the exposed pad to internal ground planes.
