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 V_S = 5 V, R_(BIAS) = 237 Ω, L_(COL) = 470 nH.
Design requires only 2 dc-blocking capacitors, 1 power-supply bypass capacitor, 1 RF choke, and 1 bias resistor.
