    Need a voltage regulator/converter... for a TTL line ckt

    Hi All, I'm designing a SP8T Switch for a switch filter bank. There are 3 TTL lines (A2 A1 A0) from the decoder. In oder to put both switches on the same side, I need a circuit to make the A2 TTL line to behave in reverse. If High-Level Input Voltage (Vh>2.0 V) the circuit will put out <.8V or...

    Basic Tripler Circuit

    I've designed frequency doubler (.005-3GHz & 1-11GHZ) using bridge quad diode using core and wire for the lower freq & microstrip for the higher frequency band. I need help on designing low frequency tripler with input from 50-150MHz & 240 -375MHz, +10dBm power input & +15Vdc. I'd like to know...

    dc-35 MHz 50Ohm-4000 Ohm Transformer

    Hi, I need help to design a tranformer to match my 50 Ohm output from a I-Q mixer to a load impedance of 4,000 Ohm. The conversion loss from my mixer is about 10.0 dB max (50 Ohm). Rf power is 0 dBm. LO is about +10 dBm. From my calculation the voltage output at I & Q output is about 70 mV...
