DESCRIPTION

The THS9000 is a medium power, cascadeable, gain block optimized for high IF frequencies. The amplifier

incorporates internal impedance matching to 50 Ω. The part mounted on the standard EVM achieves greater

than 15-dB input and output return loss from 50 MHz to 325 MHz with VS = 5 V, R(BIAS) = 237 Ω, L(COL) = 470 nH.

Design requires only two dc-blocking capacitors, one power-supply bypass capacitor, one RF choke, and one

bias resistor.
