BIAS TEE HF or VHF/UHF >100 Watt >1 Amp.

[-A3-]

I want to build 2x BIAS TEE to power relays and preamps with the following specifications:

1:
TX power: 100 Watt
Frequency: 1-60 MHz (HF + 6m)
Voltage: 12 Volt
Current: 1 Ampere

2:
TX power: 100 Watt
Frequency: 100-1400MHz (2m + 70cm + 23cm)
Voltage: 12 Volt
Current: 1 Ampere

Any of you with experience with building a bias tee for higher current and power can advise me about the L and C values?

Calculate a choke inductor with reactance greater than 500 ohms at working frequency (if your impedance is 50 ohms), and also calculate the choke wire thickness for DC current consumption greater than 1A.
The decoupling caps part of the bias tee should have very low reactance at working frequency. Place more in parallel for wideband response.

DC power consumption: 12V X 1A=12W, how to get 100W TX?

Tony, the Bias Tee is used only to supply 12V relays.

Thanks for the advise!
