HELP! substitutes needed
I'm working on a 915MHz mixer design, and just run into a challenge of unavailability of these components
1.Varactor diode BB131 (philips)
2.Feedback amplifier transistor AT-41486 (agilent)
3.Schottky diode BAT15-04W
4.RF transformer JTX-2-10T
pls I need suggestions...
RF simulation
Please I need a simulator for RF/microwave circuits
I am designing a mixer and I need to simulate my work so far because I'm doing it in stages. Please help!

i've been looking for an ocillator circuit for my project for sometime and this site has just been of help to me.
thanks for sharing
915 MHz MIXER
Pls I have this project to work on and I don't have a circuit diagram to implement it. Pls I need help cos time is running out. I have rather broken it down to its constituent block diagram
1. Local Oscillator to generate the carrier
2. A frequency multiplier in case I cannot get...
Re: 915 Mhz mixer design
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
Thanks a lot
I can use GSM, RF or bluetooth depending on the most feasible. Never heard of Zigbee.

Thanks
I've seen the site.but I don't know how readily it's available. I'll try to find out more about it
