Analog Devices Inc. ADRF5026SCCZ-EPR7

Overview

ADRF5026SCCZ-EPR7 from Analog Devices is a nonreflective silicon SPDT RF switch operating from 100 MHz to 44 GHz, featuring 3.8 dB insertion loss at 40–44 GHz, 45 dB isolation in the same band, and dual ±3.3 V supply operation. It serves as an ultrawideband signal path selector in mmWave front-ends for 5G infrastructure and military radar systems.

For engineers reviewing the ADRF5026SCCZ-EPR7 datasheet, ADRF5026SCCZ-EPR7 pinout, ADRF5026SCCZ-EPR7 application, or ADRF5026SCCZ-EPR7 equivalent, key selection criteria include its −55°C to +105°C military temperature range, 20-terminal 3 mm × 3 mm LGA package, all-off control state, and verified 50 Ω matched RF ports with no external DC blocking required.

Technical Context

The ADRF5026SCCZ-EPR7 implements a CMOS/LVTTL-compatible dual-control architecture with separate EN and CTRL inputs enabling precise all-off or RFC-to-RF1/RF2 switching states. Its nonreflective design integrates internal 50 Ω terminations on both RF1 and RF2 ports, eliminating external termination components and ensuring stable impedance across 100 MHz–44 GHz.

It operates with ±3.3 V supplies (VDD = +3.3 V, VSS = −3.3 V), delivers 40 ns 0.1 dB RF settling time, and supports hot switching up to 24 dBm across all paths. The device's thermal resistance (θJC = 423°C/W through path) requires careful PCB ground plane design due to its exposed pad thermal interface.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range of the ADRF5026SCCZ-EPR7?

The ADRF5026SCCZ-EPR7 is rated for continuous operation from −55°C to +105°C, meeting AQEC standards for defense and aerospace applications. This extended range is validated across all electrical specifications including insertion loss, isolation, and power handling-no derating is required within this interval, and thermal performance data (e.g., Figure 4) confirms stable dissipation up to 105°C case temperature.

Does the ADRF5026SCCZ-EPR7 require external DC blocking capacitors on its RF ports?

No, the ADRF5026SCCZ-EPR7 does not require external DC blocking capacitors on RFC, RF1, or RF2. All three RF ports are dc-coupled to 0 V and ac matched to 50 Ω, as confirmed in the Pin Function Descriptions table. External capacitors are unnecessary unless the connected circuit imposes a non-zero DC bias that conflicts with the switch's 0 V dc reference.

What is the meaning of "all-off control" in the ADRF5026SCCZ-EPR7?

"All-off control" means the ADRF5026SCCZ-EPR7 can simultaneously disable both RF1 and RF2 paths by setting CTRL = EN = low (0 V), placing RFC in high-isolation state relative to both outputs. This feature prevents signal leakage during standby or fault conditions and is distinct from standard SPDT behavior where one path remains active.

Is the ADRF5026SCCZ-EPR7 pin compatible with any other Analog Devices switches?

Yes, the ADRF5026SCCZ-EPR7 is pin compatible with the ADRF5027SCCZ-EP, which shares identical CC-20-4 LGA package, pin numbering, and control interface. Both devices use the same footprint and solder mask layout, allowing drop-in replacement where the lower 9 kHz frequency limit of ADRF5027SCCZ-EP is acceptable.

What supply voltages does the ADRF5026SCCZ-EPR7 require?

The ADRF5026SCCZ-EPR7 requires two independent supply rails: VDD = +3.3 V (±0.15 V) and VSS = −3.3 V (±0.15 V). These must be well-decoupled and referenced to the device's ground pins. Operation outside this dual-rail range violates Absolute Maximum Ratings and may cause permanent damage or parametric failure.
