ABSTRACT OF THE DISCLOSURE An apparatus is provided for containing information designating the frequency of operation of a synthesized radio frequency transceiver. The apparatus includes a multi-layer circuit board having upper and lower boards and at least one intermediate board disposed there between. A memory on the exterior surface of the upper board provides frequency data to a multibit output port when the memory is addressed. Memory input and output ports are connected to the upper lower and intermediate board to logical contact pad situated on the exterior surface of the lower board. Jumpers are situated on the exterior surface of said of the lower circuit board which are selectively cuttable to control predetermined characteristics of operation of the transceiver. A portion of a first of a circuit external to the apparatus is connected to a portion of a second circuit external to the apparatus through connections on the exterior surface of the lower board.
