DC1528A

Demonstration circuit 1528A is a mean-squared power detector featuring the LTC®5582 IC. The LTC5582 is a wide dynamic range mean squared RF power detector, operational from 40MHz to 6GHz. The input dynamic range with ±1dB nonlinearity is 60dB depending on frequency(from -58dBm to +2dBm, single-ended 50 ohm input). The detector output voltage slope is normally 30mV/dB and the typical output variation over temperature is ±0.5dB at 2140MHz. The DC1528A Demo Circuit is optimized for wide frequency range of 40MHz to 5.5GHz. However, input match can be optimized above 6GHz with simple external matching. Operating above 6GHz is possible with reduced performance.

• Supply voltage range from 3.1V to 3.5V at VCC = 3.3V, EN = 3.3V, TA = 25°C
• Supply current of 41.6mA at VCC = 3.3V, EN = 3.3V, TA = 25°C
