Bandwidth 100MHz, P1dB 15dBm, Gain 15dB, with SiGe BiCMOS, is it possible?

[purian]

How can i design this amplifier, the bandwidth is about 40MHz~100MHz, P1dB is 15dBm, and the Gain is about 15dB, which circuit topology can I used, is there anyone give me some advice? thanks!:?:

It's possible by applying a CasCode configuration with/without feedback.
This feedback can be series only or series and parallel combination.

Single ended and Differential pair is also possible but I don't know your PDK characteristics.
Darlington topology is an alternative.

I want to used BiCMOS 0.18um PDK, and the differential structure must be used to connect the later circuit, can the cascode configuration with/without feedback is possible? The single chip without any off-chip component is possible? thanks.

Differential Cascode is also possible with or without feedback.All you have to do is to create a balun at the input of the amplifier for single ended signal sources.
