FM PLL Exciter Design

Hi there, I have a requirement for a small FM exciter. It is to operate from 87.5 Mhz to 108 Mhz and must be tuneable in 50 Khz steps and locked by PLL. Ideally, I would like this hooked up to an LCD display which reads out the current frequency, but otherwise if you can make the Exciter accept commands via serial/spi/i2c or whatever, I can interface a uc and lcd to it. This should be designed for SMT in mind as I want it as small as possible (no spider solder hackers please!). Output power should be 1 Watt, however if you can make it variable 1-5 Watt, that would be ideal. Common broadcasting rules should be taken into account (eg, 2nd harmonic -60dB from the 1st etc.), so you should have relevant RF experience. Stereo is not a requirement. Input will be line level audio (~750mV). The price for this job is quite low, but if you come up with everything as I want it, there will most definately be a good bonus instore. I'm sure you will have some questions, so please ask. ## Deliverables I would like.. 1) Circuit Design 2) Any Source Code and Compiled Code 3) PCB Design 4) Ownership of all of the above (unless previously shared) 5) Good support :) I can reimburse for parts if you want to send me a prototype. ## Platform N/A
