Hi, I want to generate 500 MHz two sine waves which are opposite each other and oscillate with dc offset as shown in below figure.
The voltage range of the oscillation is 0 V(min)~1.8 V(max) or 4.5 V~1.8 V.
I try to find some circuits but there is no information about this. And i am not a circuit engineer.
How i can generate these sine waves using the commercial ICs and DC supply ?

Additionally, I wonder whether the Phase locked loop circuit with a sine wave input has also sine wave output or not.
Thank you,

Thank you,
You mean RC or LC filter?? Is it possible to convert the high freq. clk signal from oscillator to sine wave using the lumped filter?
I will use the sine wave as input signals in the sense amplifier or flip flop for research.

A single NPN can amplify a waveform, and provide two outputs, one in phase, the other inverted. DC offset is automatic.



A lot of adjusting may be necessary. It may be easier to use two independent transistors to create two separate outputs.

Hi,

I'm not familiar with HF

I assume generating the 500MHz is not that big problem, but generating an exact 180° phase shift..

What about a "transformer style solution". Like a single primary input and a center taped output (or two independet output windings).
..just an idea for the HF guys here...
