PIN VIDEO OUT RF I N * 50-ohm source impedance, 2 KΩ||50 pF output load, +5 Vd c. † Pin = –15 dBm . ^ Vout = 100 m V. ^^ 3 dB NF , 1 MHz Bandwidth. ‡ 50% RF to 10 or 90% Video. This unit is DC coupled and em ploys a R F choke at the input (DC short). If the application calls for the input to sink current there w ill be approxim ately an additional 1 m V of output offset volt- age for each 3 m A of current. Sink current should be limited to 100 m A m ax to avoid choke burnout. For higher supply voltages, up to ±15 volts, the positive supply pin m ust include a series cur- A verage pow er detection is obtained at pow er levels below approxim ately –13 dBm . For best pulse response the supply pins should be bypassed w ith an additional 1.0 µF capacitor. The unit contains 0.01 µF internal capacitors.
