LTC5531ES6 Evaluation Kit
Linear Technology Inc.
Description
Demonstration circuit 710 is used to evaluate the LTC®5531ES6, RF power detector with integrated output buffer and voltage reference. The LTC5531ES6 has provisions for enable and offset adjustments. The LTC5531ES6 converts an RF input signal at pin 1 (RFin) to a DC voltage at pin 5 (Vout). The RF input frequency range is 300 MHz to 7000 MHz. Maximum input power is 10 dBm. The output voltage at Vout will start at an initial DC value of typically 120 mV +/- 35 mV. When the RF signal is applied, the output voltage will increase. The optional R1 termination resistor and C3 output shunt capacitor are not placed on the PCB. Resistor R3, from pin 4 (offset adjustment pin) to ground is not placed. The demo circuit has R2, a 22K pull-up resistor, which provides a logic HIGH for the Enable pin (IC Enabled). Enable pin E3 should be left unconnected for initial tests and measurements.
