915 Mhz mixer design

Did you receive any specs along with the project?

The HMC483MS8G & HMC483MS8GE are high
dynamic range passive MMIC mixers with integrated
LO amplifi ers in plastic surface mount 8 lead Mini
Small Outline Packages (MSOP) covering 0.7 to 1.4
GHz. Excellent input IP3 performance of +33 dBm for
down conversion and +30 dBm for up conversion is
provided for 2.5G & 3G GSM/CDMA applications at
an LO drive of 0 dBm. With an input 1 dB compression
of +24 dBm, the RF port will accept a wide range of
input signal levels. Conversion loss is 9.0 dB typical.
The DC to 350 MHz IF frequency response will satisfy
GSM/CDMA transmit or receive frequency plans
confi gured for low side LO. The HMC483MS8G &
HMC483MS8GE are pin for pin compatible with the
HMC485MS8G & HMC485MS8GE which are 1.7 -
2.2 GHz mixers with LO amplifi ers.

No I have not received any specs

Added after 2 minutes:

i think I need to design using diodes or tansistors
i will be very happy to get the circuit design

Yeah, just use a HMC483MS8G. Then wait for a response. Engineering at its best.
