Hi,
I've got the ouptut of a PLL (~1 GHz, 0dBm) and the input of a tranceiver chip, connected by about 7cm microstrip line. However, I need to amplify the PLL's output by about 12dB, what I'm going to realize with a MMIC amplifier.
What's the best point to place the amplifier:
a) right behind the PLL output -> to amplify a clean signal, without amplifying other signals radiating into my microstrip line
b) right before the transceiver input -> to transmit only a low power signal on the 7cm microstrip line = to minimize radiating from my microstrip line into other parts of the circuit?
Thanks for any help!
