14. Passive Equalization:
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
- 2.2 dB
Confidential

15. Effects of Loss in Time/Frequency:
THE CHALLENGE IS NOT
THAT THERE IS LOSS, IS
THAT THE LOSS IS
FREQUENCY DEPENDENT!!!
Confidential

16. Tests Results: ATE to Test Fixture End
Simulation Results:
Frequency Domain:
5.5GHz Bandwidth Extension Jitter Reduction = 10.6ps = 63% (16.8 – 6.2ps)
Measured Results:
No Equalizers ATE Integrated EQ only Int. EQ & Test Fixture EQ
(Integrated EQ & Test Fixture EQ) Jitter Reduction = 8.9ps = 35.7% (24.9 – 16.0ps)

17. Equalizer Market Linear Amp.:
 Product Explanation:
 Equalizer Application for:
●
Driver/Amplifier Gain flattening.
Confidential

18. 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.

22. Duo Binary Application Requires TFT’s Filter:
Filter Output
(Duo Binary)
Driver Output
 9th order absorptive filter
produce dual binary
signal to be injected into
the laser modulator.
 Filters exhibit flat group
delay and –15 dB return Signal on the Fiber
loss well beyond the cutoff
Confidential frequency.

23. Receiver Sensitivity Applications:
• Signal is converted from optical back to electrical.
TFT Filter
 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.

24. 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

26. TFT Custom Filter Capabilities - Diplexer Simulations

27. TFT Custom Filter Capabilities - Diplexer
NRE
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

28. TFT 10 Ghz & 20 Ghz
Crossover Chip
Confidential

29. TFT High frequency Crossover Chip
Initial Customer Request
 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;
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

30. TFT 20 Ghz Crossover Chip
History
 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.
