1. A tuning circuit for an integrated multistage radio frequency (RF) amplifier having an inter-stage matching network and a voltage supply input, comprising: a printed circuit board (PCB) trace for coupling a DC voltage source to the voltage supply input; and a first discrete capacitor and a second discrete capacitor, both connected in shunt between the PCB trace and ground, for tuning inductance on the voltage supply input to improve performance of the inter-stage matching network within the integrated multistage RF amplifier.
