Description:SWR200 is a precision Integrated Circuit providing an ultra-stable sine wave output of +7.071V at ±0.5% initial accuracy and a temperature coefficient as low as 20 ppm/°C over the full military temperature range. This extreme accuracy is made possible by a chopper-based AGC circuit. The temperature characteristic of the chopper circuit compensates the typical nonlinearity of the internal DC zener reference resulting in a near linear amplitude-temperature characteristic. Frequency of the SWR200 is programmab
Apex Microtechnology recommends a 4-layer PCB with a solid ground plane, and a minimum of 10 mils of clearance around the device. A thermal pad on the bottom of the device should be connected to a large copper area on the PCB to dissipate heat.
The SWR200M requires a bias voltage of 15V to 30V, and a bias current of 1mA to 10mA. A voltage regulator and a current limiting resistor can be used to set the bias voltage and current. The datasheet provides a recommended bias circuit.
The SWR200M can handle up to 200W of continuous power, and up to 400W of peak power for short durations. However, the device's power handling capability is dependent on the PCB layout, thermal management, and operating conditions.
Apex Microtechnology recommends using voltage and current limiting circuits to protect the device from overvoltage and overcurrent conditions. A zener diode or a voltage regulator can be used to limit the voltage, and a current limiting resistor or a fuse can be used to limit the current.
The thermal resistance of the SWR200M is 2.5°C/W. To manage heat dissipation, Apex Microtechnology recommends using a heat sink with a thermal interface material, and ensuring good airflow around the device. The PCB layout should also be designed to dissipate heat efficiently.
