Avantek Products HEWLETT PACKARD | Voltage Controlled Signal Limiter 5 to 1000 MHz Technical Data Features * 6 to 1000 MHz Frequency Coverage Voltage Controllable VSWR < 2.0:1 Applications Protection for Detectors, Mixers, and Amplifiers * Cascadable Gain Control EW Receiver Circuits Wideband System Protection Description The GPL-1001 is a voltage con- trolled signal limiter which covers the 5 to 1000 MHz frequency range. This thin-film limiter features a voltage programmable output level with an input level as high as +26 dBm. It has low VSWR, low insertion loss, excel- lent. second- and third-harmonic suppression, and very low AM-to-PM conversion. Recovery from fully saturated input levels is less than 50 nanoseconds, The GPI-1001 is provided in the TO-12 package. GPL-1001 Pin Configuration TO-12 GROUND CASE GROUND See Section 5 for detailed case drawings. } Electrical Specifications* (Measured in a 50-ohm system @ +15 VDC nominal unless otherwise noted) Insertion| Limited Loss | Output Third- | Second- Operating Output Power | Smatl | Power Harmonic | Harmonic Bias Maximum | Maximum Frequency (@ +10 dBm P,,} Signal | Flatness VSWR Power Power Current] Recommend |Recommend Response (MHz) dBm (+dB) | (2dB) Typical (dBm) (dBm) DC (mA) | Input Power Bias Model Minimum Maximum Typical | Typical |Input Output; Typical | Typical | Nominal Typical) (dBm) (voc) GPL-1001 5-1000 -4.0 5.0 1.0 20 2.0 ~12 30 415 5 +26 +20 (-8 typ) * Limiter incorporates DC coupled diodes shunted to ground at input pin.
