Liepa the Power of Attorney is on file and can be provided when so requested. Re: Certification for Delphi Delco 15270437 Receiver Model: 15270437 FCC ID: L2C0022R IC: 3432A-0022R REQUEST FOR CONFIDENTIALITY Pursuant to 47 CRF 0.459, Delphi Delco requests that a part of the subject application be held confidential. This comprises Exhibits (5) Schematics (10) Parts List (Part of Exhibit only) Delphi Delco has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship.

RF signal is received by an external antenna and then goes to the circuit thru a mounted coax connector. The signal goes to a 315 MHz SAW filter a LNA preamplifier and finally applied to Infineon Receiver IC TDA5211. This receiver IC has a LNA Stage one mixer, one IF filter at 10.7 MHZ a ASK detector, a low pass data filter of 5 KHz and a data slicer circuit. Received digital Data is further processed by the master micro- controller IC. The LO signal which is also applied to the mixer stage is generated by a Frequency synthesizer, which consist of a crystal controlled Reference oscillator running at 10.178 MHz. a VCO running at 651.4 MHz which is divided by 2 and applied to the mixer to get the 10.7 MHz IF frequency. The VCO (651.4 MHz) is also divided by 64 in this process.
