The **ADRF5080BCCZN-R7** is a high-performance, silicon-based, reflective SPDT (Single Pole Double Throw) switch designed by Analog Devices. It is specifically engineered for high-frequency applications, typically found in telecommunications and radar systems. --- ### 1. General Specifications Below are the primary technical parameters for the ADRF5080: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 20 GHz to 60 GHz | | **Insertion Loss** | 2.5 dB (Typical at 60 GHz) | | **Isolation** | 35 dB (Typical at 60 GHz) | | **Switching Speed** | 100 ns (Rise/Fall time) | | **Power Handling** | 28 dBm (P0.1dB) | | **Control Interface** | CMOS/LVTTL Compatible | | **Package** | 20-terminal LGA (3 mm x 3 mm) | --- ### 2. Key Features and Architecture * **Silicon-on-Insulator (SOI) Process:** Unlike traditional GaAs (Gallium Arsenide) switches, this part uses SOI technology. This allows for better integration, lower power consumption, and eliminates the need for external DC blocking capacitors if the RF lines are at 0V DC. * **Wideband Performance:** It operates effectively from 20 GHz up to 60 GHz, making it suitable for 5G mmWave and satellite communications (Ka-band and V-band). * **Reflective Design:** As a reflective switch, when a port is in the "OFF" state, the RF energy is reflected back rather than being absorbed by an internal load. * **Simplified Control:** It features an on-chip driver, requiring only a simple positive supply voltage ($V_{DD}$) and standard logic levels to switch paths. --- ### 3. Pinout and Integration (Functional View) The device is housed in a compact Land Grid Array (LGA) package. Here is a high-level overview of the pin functions: | Pin Type | Function | | :--- | :--- | | **RFC** | RF Common Port (Input/Output) | | **RF1, RF2** | RF Switched Ports | | **VDD** | Positive Supply Voltage (3.3V typical) | | **CTRL** | Logic Control Pin (Determines path RFC to RF1 or RF2) | | **GND** | Ground - critical for thermal and RF performance | --- ### 4. Typical Applications * **5G mmWave Infrastructure:** Used in beamforming and antenna switching. * **Military Radar:** High-frequency signal routing in EW (Electronic Warfare) systems. * **Test & Measurement:** Used in high-speed automated test equipment (ATE). * **Satellite Communications:** Earth stations and high-throughput satellite terminals. --- ### 5. Part Number Breakdown * **ADRF5080:** Base part number. * **BCCZ:** Package designator (LGA). * **N:** Temperature range/feature set. * **R7:** 7-inch reel packaging (standard for automated SMT assembly). ---
