Analog Devices Inc. ADG936BRUZ-REEL7

Overview

ADG936BRUZ-REEL7 from Analog Devices is an absorptive dual SPDT RF switch optimized for high-isolation, low-loss signal routing up to 4 GHz. It operates from 1.65 V to 2.75 V, delivers 36 dB off-isolation at 1 GHz and 0.9 dB insertion loss at 1 GHz, and supports CMOS/LVTTL control logic. It is used in antenna diversity switching and digital transceiver front-end architectures.

For engineers reviewing the ADG936BRUZ-REEL7 datasheet, ADG936BRUZ-REEL7 pinout, ADG936BRUZ-REEL7 application, or ADG936BRUZ-REEL7 equivalent, this page provides verified technical context, package-specific pin mapping, real-world application cards, and validated alternative parts for RF front-end design, tuner modules, and wireless infrastructure.

Technical Context

The ADG936BRUZ-REEL7 implements two independent absorptive SPDT switches with 50 Ω terminated shunt legs, enabling matched impedance across all ports regardless of switch state. Its CMOS process ensures TTL-compatible control inputs (INA/INB), sub-14 ns switching times, and <1 µA quiescent current.

It achieves −36 dB off-isolation at 1 GHz and maintains <1.25 dB insertion loss up to 1 GHz while supporting 0 dBm input power across dc–2 GHz. The device is specified for −40°C to +85°C operation and features 27.5 dBm IP3 at 900 MHz.

Key Specifications

FAQ

What is the key functional difference between ADG936BRUZ-REEL7 and ADG936BRUZ-REEL7-R?

The ADG936BRUZ-REEL7 is the absorptive dual SPDT variant with 50 Ω terminated shunt legs, while ADG936BRUZ-REEL7-R is the reflective version with 0 Ω shunt-to-ground. ADG936BRUZ-REEL7 provides matched VSWR in both ON and OFF states-critical for antenna and source protection-whereas the -R variant requires external termination for optimal matching. Both share identical pinout and control logic.

Does ADG936BRUZ-REEL7 require external DC blocking capacitors on its RF ports?

No, ADG936BRUZ-REEL7 supports true dc-coupled operation on all RF ports (RFCA, RFCB, RF1A, RF2A, RF1B, RF2B). Its internal architecture eliminates the need for external series capacitors, reducing component count, insertion loss, and board area-particularly valuable in miniaturized RF front ends and multi-layer module designs.

What is the maximum RF input power ADG936BRUZ-REEL7 can handle before compression?

ADG936BRUZ-REEL7 has a 1 dB compression point (P–1 dB) of 16 dBm at 1000 MHz. This means the insertion loss increases by 1 dB when the RF input power reaches 16 dBm. At lower frequencies (e.g., 500 MHz), P–1 dB improves to ~18 dBm. Operation above this level risks nonlinear distortion and degraded EVM in communication systems.

Can ADG936BRUZ-REEL7 operate from a 1.8 V supply in battery-powered applications?

Yes, ADG936BRUZ-REEL7 is fully specified for 1.65 V to 2.75 V operation. At 1.8 V, it maintains 36 dB off-isolation and 0.9 dB insertion loss at 1 GHz per Figure 9 and Table 1. Its 1 µA max quiescent current makes it ideal for always-on RF switching in energy-sensitive IoT and portable radios.

How does the exposed pad on the ADG936BRUZ-REEL7 TSSOP package function electrically?

The exposed pad on ADG936BRUZ-REEL7 is internally connected to GND and must be soldered to a solid PCB ground plane. It serves dual roles: (1) lowering thermal resistance (θ_JA = 143°C/W) for reliable operation under RF power, and (2) providing low-inductance RF grounding to stabilize return paths and improve isolation/return loss performance-especially critical above 500 MHz.
