About the job
Product Function
Maps 4 (A) RF ports to any of 16 (B) ports, with 1 RX (B → A) and 3 TX (A → B).
Uses 31 SP4T (BGSA14GN10) and 5 high-isolation SP4T (PE424450) in a tree topology.
Controlled via I2C with three 16-bit IO expanders (MCP23017), interfacing with an external ESP32 MCU.
Performance
Isolation: ~100 dB between TX and RX, dual ground planes for RF RX.
Insertion/Return Loss: Minimal additional loss beyond switch matrix.
RF Range: 860–960 MHz, 50Ω stripline waveguides for strong isolation.
Use Environment
Indoor setup, powered by an external 3.3V ESP32-based PoE device.
Requires RF shielding and optimized PCB layout for minimal interference.
Deliverables
Full turnkey solution: design, prototyping, testing, and 20-unit manufacturing.
Includes schematics, layout, BOM, firmware configs, and performance analysis.
Quote to include cost-performance trade-offs for alternative configurations.
