Equalization in the Freq. Domain:

Goal of Passive Equalization: Flatten the loss through

the working bandwidth. Extend the bandwidth

performance.

50cm Stripline Example: -3dB Bandwidth Extension:

4.5 GHz (2.73 GHz to 7.25 GHz)

Fund. Freq. “Normalized” Loss: Trace & Pogo Loss + Internal EQ

- 4.4 dB Resultant f-Domain Function

THE CHALLENGE IS NOT THAT THERE IS LOSS, IS THAT THE LOSS IS FREQUENCY DEPENDENT!!!

Effects of Loss in Time/Frequency:

Equalizer Market Linear Amp.: Product Explanation:

Equalizer Application for: Driver/Amplifier Gain flattening.

Confidential

Equalizer Market - UWB:

Equalization – Channel tilt – the wider the channel the greater the attenuation tilt between high and low frequencies in the channel. To correct the tilt distortion, equalization can be performed in the receiver or reverse tilt pre-distortion can be done in the transmitter.

Duo Binary Application Requires TFT’s Filter:

Driver Output

Signal on the Fiber

Filter Output (Duo Binary)

9th order absorptive filter produce dual binary signal to be injected into the laser modulator.

Filters exhibit flat group delay and –15 dB return loss well beyond the cutoff frequency.

Confidential

Receiver Sensitivity Applications:

• Signal is converted from optical back to electrical.

The combination of the photodiode and Trans-impedance amplifier convert optical power to current to voltage.

TIA bandwidth, noise, group delay (eye quality) are critically influenced by the equivalent circuit of the input photodiode (laser).

Using high order low pass filter can recover some of the “damaged” eye pattern.

TFT Custom Passive Filters

TFT has the capability for fast turn arounds, from conception to production. The following is an example of a custom requirement for a diplexer. The only information supplied were the frequencies.

From the customer: We have a new project beginning that needs a highpass/lowpass duplexer to split 1230 MHz (lowpass) and 1570 MHz (highpass). I would prefer this to be done with RC/RCL circuits, but we might also consider LTCC as an option. We do not have a solution to combine the 2 bands at this moment so a solution from you would be very good

TFT Custom Filter Capabilities - DiplexerNRE

TFT approaches NRE’s with a multi-phase approach which targets important stages in the filter design. At these critical stages the customer can elect to discontinue, or proceed with the NRE based on TFT’s findings. The targeted critical stages usually consist of size, specifications, and/or cost.

In the Diplexer example size is the issue with a 1206 size SMT BGA as the target. The following is a breakdown of how the design/NRE stages have or will be scheduled.

• Customer supplies design requirement

•TFT performs initial simulations to determine feasibility. No cost

•TFT supplies initial simulations and proposal to customer which produces targets specs.

•Phase one - Mask and Layout based on proposed specs to determine package size <$1K

•Phase two - Initial lot run w/ 4 designs to determine optimum performance. $1.2K

•Phase Three - 20 deliverable filters, Test Module, and finalization of specs. $1.3K

TFT 10 Ghz & 20 GhzCrossover Chip

Confidential

TFT High frequency Crossover Chip

The 20 Ghz crossover Chip was designed as a result of a customers idea for a needed product not currently available. Highest bandwidth available was a 7Ghz device

In order to address cost/performance issues we also developed a 10Ghz crossover chip;

Initial Customer Request

Features and Advantages:This high frequency crossover device is a surface mount component that provides excellent signal integrity characteristics beyond 20 GHz to be achieved while allowing circuit routing transitions with traditional BGA manufacturing techniques on single layer board layouts that normally require significantly more expensive multi-layer RF

and microwave PCB manufacturing or RF cabling assemblies.

Confidential

TFT 20 Ghz Crossover Chip

Customer request for a 20GHz plus performance jumper to allow for HF routing on 40 Gbps optical circuits.

This is important because the complexity of the circuit does not require multilayer PCB. Plus, Multilayer circuits boards could cost several thousands of dollars extra. It seems just one or two crossovers could facilitate difficult circuit layouts without the multilayer costs and problems.
