RF, wireless, and control system design consulting
Dan Tatum started Wireless and Control Systems LLC to design electronic devices for low quantity, high-mix products for customers in the medical, robotics, and aerospace industries.
ESP32 based Arduino compatible remote control system with 8 PWM Servo outputs, SparkFun QWIIC / Adafruit STEMMA I2C, and PMOD 2A SPI connections for easy customization.
This guide is to design a prototype 1W amplifier for 2200-2400MHz S-band SATCOM application on 20 mil Rogers RO4350B.
The design facilitates discrete input preselect band pass filter, matching network and bias for SOT-89 footprint, and discrete output low pass filter prototypes.
