Applications Information

Application Circuit

The CMD201 is biased with a positive drain supply, a negative gate1 supply and a positive gate2 supply.

Performance is optimized when the drain voltage is set to +10 V. The recommended gate1 and gate2

voltages are -0.55 V and +5 V respectively.

Turn ON procedure:

1.Apply gate voltage Vgg1 and set to -0.55 V

2.Apply drain voltage Vdd and set to +10 V

3.Apply gate voltage Vgg2 and set to +5V

Turn OFF procedure:

1.Turn off gate voltage Vgg2

2.Turn off drain voltage Vdd

3.Turn off gate voltage Vgg1

DC-20 GHz Distributed Power Amplifier

Biasing and Operation

Note: Drain voltage (Vdd) must be applied through a broadband bias tee or external bias network.

External DC block is required on RF input.
