The **ADRF5022BCCZN-R7** is a high-performance, silicon-based, reflective **Single-Pole Double-Throw (SPDT) switch** manufactured by Analog Devices. It is designed for high-frequency applications, particularly within the 100 MHz to 45 GHz range. --- ### ## Technical Specifications Overview Below are the core electrical and mechanical characteristics of the ADRF5022: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 100 MHz to 45 GHz | | **Insertion Loss** | 2.0 dB (typical at 45 GHz) | | **Isolation** | 38 dB (typical at 45 GHz) | | **Switching Speed** | 10 ns (Rise/Fall time) | | **Power Handling (P0.1dB)** | 27 dBm | | **Control Interface** | CMOS/LVTTL compatible | | **Package Type** | 20-terminal LGA (3.00 mm x 3.00 mm) | | **Operating Temperature** | -40°C to +105°C | --- ### ### Key Electronic Features 1. **Broadband Performance:** Unlike many Gallium Arsenide (GaAs) switches, this Silicon-on-Insulator (SOI) part provides a flat response across a massive bandwidth (up to 45 GHz), making it ideal for wideband instrumentation. 2. **Reflective Architecture:** This is a **reflective switch**, meaning that when a port is in the "OFF" state, the RF signal is reflected back rather than being terminated into a 50Ω load. This is useful for high-power tolerance but requires careful system design to manage reflections. 3. **No Negative Supply Required:** The ADRF5022 operates on a positive supply voltage (typically +3.3V) and does not require a negative bias, simplifying the Power Management Integrated Circuit (PMIC) design on the PCB. 4. **High ESD Robustness:** The SOI process provides superior Electrostatic Discharge (ESD) protection compared to traditional GaAs switches, increasing the reliability of the assembly. --- ### ### Application Use Cases * **Test and Measurement:** High-speed signal routing in oscilloscopes and network analyzers. * **5G Infrastructure:** Beamforming and antenna switching in mmWave base stations. * **Military & Aerospace:** Radar systems and electronic warfare (EW) receivers. * **Satellite Communications (SATCOM):** Signal switching in ground stations. --- ### ### Pin Configuration & Part Numbering The "R7" suffix in the part number indicates the packaging format: **7-inch Tape and Reel** (typically 500 units). The "BCCZN" refers to the Lead-frame Chip Scale Package (LFCSP/LGA) which is RoHS compliant.
