The **ADRF5250BCPZ-R7** is a high-performance, silicon-on-insulator (SOI), non-reflective SP5T (Single-Pole, Five-Throw) switch designed for wireless infrastructure and high-frequency applications. --- ## 1. Technical Specifications The following table summarizes the key electrical and physical characteristics: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 100 MHz to 6.0 GHz | | **Insertion Loss** | 0.8 dB (at 2.0 GHz) | | **Isolation** | 38 dB (at 2.0 GHz) | | **Input P1dB** | 35 dBm | | **Switching Speed** | 250 ns | | **Operating Voltage** | 3.3 V to 5.0 V | | **Package** | 24-lead LFCSP (4mm x 4mm) | | **Termination** | Non-reflective (50 Ω internal) | --- ## 2. Key Features and Architecture The ADRF5250 is engineered for modern RF front-ends that require high power handling and low signal distortion. ### Non-Reflective Design This device is "absorptive" or non-reflective. When a specific RF path is in the "OFF" state, the ports are internally terminated to a 50 Ω load. This prevents signal reflections that could otherwise damage power amplifiers or cause instability in the RF chain. ### Silicon-on-Insulator (SOI) Technology Unlike older Gallium Arsenide (GaAs) switches, the SOI process allows for: * **Integrated CMOS/LVTTL Control:** It can be interfaced directly with microcontrollers without level shifters. * **High Linearity:** Maintaining low harmonic distortion even at high power levels. * **No DC Blocking Caps:** In many configurations, if DC is not present on the RF line, external blocking capacitors may be omitted, saving PCB space. ### Control Logic The switch uses a 3-bit binary control interface to select one of the five outputs (RFC to RF1 through RF5). --- ## 3. Typical Applications The ADRF5250BCPZ-R7 is primarily found in: 1. **5G/4G Macro & Small Cell Base Stations:** Used for signal routing and antenna selection. 2. **Test and Measurement Equipment:** High-speed switching for signal analysis. 3. **Military Radios:** Robust performance in demanding environments. 4. **WLAN/Wi-Fi 6 Systems:** Handling high-frequency bandwidths up to 6 GHz. --- ## 4. Packing and Ordering Info The suffix **-R7** indicates the packaging format: * **R7:** Denotes a 7-inch tape and reel, typically containing 1,500 units. * **BCPZ:** Refers to the Lead-Frame Chip Scale Package (LFCSP) which is RoHS compliant.
