Hi,
I am designing an instrument using HMC547ALP3E GaAs MMIC SPDT NON-REFLECTIVE SWITCH, DC - 20 GHz.
This switch requires a 0 to -5V differential signal for operation. The datasheet for these devices provides a sample
circuit that converts 0to +5V signal to negative range to drive these circuits.
However I am concerned if this driver circuit is capable of working at frequency of 100 MHz. Hence I was trying to build
a driver circuit using ECL gates and a -ive supply rail. However I was concerned about the ECL circuit not working due to small
voltage swing associated with ECL circuits. Any work around solutions one can think off and suggest?
Regards
Asimov
