摘要: A wide bandwidth linear amplifier (10) that has an operating band in excess of 1 GHz mounts the high power dissipating components (11) of the amplifier (10), and the components 917, 18) that control the high frequency gain and stability of the amplifier (10) onto a daughter board (32) that has a high thermal conductivity. The daughter board (32) and the remaining circuit components (21, 22, 23, 24, 26a, 26b) are then mounted on a mother board (31) that has a lower thermal conductivity. The assembly (30) reduces the circuit's parasitic inductance (46, 47, 48, 49) and parasitic capacitance (51, 52), and provides unconditional stability at high frequencies.
