Analog Devices Inc. ADRF5048BCCZN

Overview

ADRF5048BCCZN from Analog Devices is a nonreflective silicon SP4T RF switch operating from 100 MHz to 45 GHz, designed for high-frequency signal routing in mmWave systems. It delivers 1.4 dB typical insertion loss at 18 GHz, 41 dB typical isolation at 18 GHz, and handles 30 dBm RF power through path with dual ±3.3 V supplies - enabling use in 5G base station front-ends and test instrumentation.

For engineers reviewing the ADRF5048BCCZN datasheet, ADRF5048BCCZN pinout, ADRF5048BCCZN application, or ADRF5048BCCZN equivalent, key selection criteria include its ultrawideband 100 MHz–45 GHz coverage, nonreflective 50 Ω architecture, 24-terminal LGA package compatibility, and CMOS/LVTTL-compatible digital control interface with EN/LS/V1/V2 logic sequencing.

Technical Context

The ADRF5048BCCZN implements a silicon-on-insulator (SOI) nonreflective SP4T topology with internal 50 Ω terminations on all off-state RF paths, eliminating external matching networks. Its bidirectional RF paths support hot switching up to 30 dBm at RFC while maintaining <4.0 dB insertion loss and >35 dB isolation across the full 45 GHz band.

Digital control uses four pins - EN (global enable), LS (logic select), V1, and V2 - to configure port selection per a truth table defining eight valid states including all-off and mirrored port mapping. The device requires dual ±3.3 V supplies and features 20 ns on/off time and 60 ns 0.1 dB RF settling time.

Key Specifications

Pinout & Package

The ADRF5048BCCZN is housed in a 3 mm × 3 mm, 24-terminal land grid array (LGA) package (CC-24-14) with exposed thermal pad. All RF ports (RFC, RF1–RF4) are DC-coupled and internally matched to 50 Ω, eliminating need for external DC blocking capacitors when RF line potential is 0 V.

FAQ

What is the maximum RF input power the ADRF5048BCCZN can handle in hot-switching mode?

The ADRF5048BCCZN supports 30 dBm hot-switching RF input power at the RFC port across 0.3 GHz to 40 GHz when case temperature is ≤85°C. At 105°C operation, this rating degrades by 3 dB due to thermal derating. This specification is verified per Analog Devices' power derating curves (Figures 2 and 3) and applies only when EN is low and proper supply sequencing is followed.

Does the ADRF5048BCCZN require external DC blocking capacitors on its RF ports?

No, the ADRF5048BCCZN does not require external DC blocking capacitors on RFC or RF1–RF4 ports when the RF line potential is 0 V DC. All RF ports are DC-coupled and internally matched to 50 Ω. External DC blocks are needed only if the connected RF line operates at a nonzero DC bias voltage - a condition explicitly called out in the Applications Information section of the ADRF5048BCCZN datasheet.

How does the LS pin affect port selection behavior in the ADRF5048BCCZN?

The LS (Logic Select) pin configures the truth table mapping between V1/V2 logic states and RF path activation. When LS = low, V1/V2 select RF1–RF4 in standard binary order; when LS = high, the same V1/V2 combinations select ports in mirrored order (e.g., V1=H/V2=L selects RF3 instead of RF2). This feature enables flexible routing without firmware modification - a documented capability in Table 6 of the ADRF5048BCCZN datasheet.

What is the thermal resistance (θJC) of the ADRF5048BCCZN for the through-path configuration?

The junction-to-case thermal resistance (θJC) of the ADRF5048BCCZN is 100°C/W for the through-path configuration, measured from channel to package bottom under simulated conditions with the EPAD held at 105°C. This value assumes optimal PCB thermal design with filled vias connecting the exposed pad to internal ground planes - a requirement specified in the Thermal Resistance section of the ADRF5048BCCZN datasheet.

Is the ADRF5048BCCZN pin-compatible with other devices in the ADRF504x family?

Yes, the ADRF5048BCCZN is pin-compatible with ADRF5049BCCZN, ADRF5042BCCZN, and ADRF5043BCCZN per the General Description and Pin Configuration sections of its datasheet. This compatibility extends to physical footprint, solder pad layout, and terminal function mapping - enabling drop-in replacement in existing PCB designs where functional requirements align.
