1 Definition of the CDDL

The Complementary Dispersive Delay Line (CDDL) uses a highly sophisticated SAW (Surface Acoustic Wave) filter device that incorporates two filters within a single device. It is required for

the operation of the nanoNET TRX Transceiver.

While most devices have two ports, the CDDL consists of three ports, as shown below.

Port A = Pin B + Pin H

Upchirp and Downchirp

Port A is the common input port. The group delay of the filter from the input to one of the outputs is characteristic for these filters.

The respective impulse response for the dispersive Delay Line 2 (DL2) is an Upchirp (Linear frequency modulation, where frequency increases in time).

The other output is complementary to this, meaning that the impulse response for Delay Line 1 (DL1) is a Downchirp (Linear frequency modulation, where frequency decreases in time).

Within the nanoNET system, the CDDL is responsible for distinguishing between two possible incoming signals generated by another nanoNET TRX Transceiver. This received signal is either an Upchirp or a Downchirp. Both of these signals have the same center frequency and the same bandwidth so that the difference occurs only in the phase information.

This phase information is enough for the CDDL to compress a pulse at one output po rt and expand it at the other (that is, to extend the incoming signal to the doubled duration). In this way the CDDL acts like a matched filter for one of the possible transmitted pulses.

Balanced Mode

Also, within the nanoNET system, the CDDL is directly connected to an RF transceiver. As this transceiver has a differential output and input, the filter is used in a balanced mode.

According to this balanced mode, the housing has 6 signal pins – two on each side and two in the center on opposite sides. The detailed pinning is described on the Balanced Filter (Bottom View) on page 3 and Pad Landing (Top View) – Proposal on pa ge 4. All other pins are co nnected to ground and at least one of them should be connected with the ground of the PC board.

In the illustration below, the signal pins are connected to strip lines. They are designe d with a width of 0.91 mm to be able to go through two pins to con n ec t bo th lines of po rt A from on e side.

On a typical PC board (FR4 of height 0.51 m m and copper thickness 35 mm, ance of these lines is about 50

1. The center frequency of the CDDL is the common center frequency of both test signals (up-chirp and downchirp) for which the run time difference of the compressed pulses is equal.

2. The averaging is done over the signal bandwidth from 210 to 290 MHz.

3. Referred to average insertion loss.

4. The gradient of dispersion includes always Fresnel ripples; therefore, the average (linear interpolation) is decisive.

5. Delay of a compressed pulse relative to the center position of the incoming chirp signal. This parameter is most sensitive against changes of temperature. Therefore a large range is specified.

6. See footnote 5.

7. This is most important to distinguish between the respective output ports of the 3 ports in Figure 1: <Emphasis Footnote>"Complementary Dispersive Delay Line schematic" on page 1–1.
