There are several QRP clubs that have published documentation on this small transceiver: I remember the G-QRP that published "The Pixie File" a pdf with a collection of schematics, easily available on the internet.

A classic circuit and a favorite in the QRP community. A QRP SSB/CW Transceiver for 14MHz -- Part 1. QST December 1989, pp. 18-21. Exotic circuitry and hard to find components aren't necessary if you want to build excellent performance into a home-brew SSB/CW transceiver: Careful design is the key.
Among the guys I work, QRPs seem to be the most common homebrew project, second only to building antennas. Therefore this chapter describes a simple QRP design I have settled on. I use my QRPs as stand-alone transmitters or I use them to drive a final amplifier to produce higher power, 25 to 100 watts.

Figure 1 — Detailed schematic diagram and parts list for the RF portion of the Universal QRP transmitter. Resistors are 1 ⁄ 4 W, 5%. A kit of component parts is available from Kanga US. 7 C10 is a VXO capacitor placed in series with the crystal to provide some frequency adjustment around the crystal frequency.
FREQUENCY CONVERTERS ARE BASIC. building blocks of RF equipment. You'll find them wherever there's a need to shift the RF carrier of a signal from one frequency to another, such as in any modern radio receiver.
