• Low Power Dissipation (1W at Vo=6V)
• Very Low Rail Ripple
• 25 ps Edge Rates (20/80)
• Small Form Factor
- 11.4 x 8.9 x 2 mm

• Evaluation Board Available.
Description
The TriQuint TGA4953-EPU is part of a series of surface
mount modulator drivers suitable for a variety of driver
applications and is compatible with Metro MSA standards.
The 4953 consists of two high performance wideband
amplifiers combined with off chip circuitry assembled in a
surface mount package. A single 4953 placed between
the MUX and Optical Modulator provides OEMs with a
board level modulator driver surface mount solution.
The 4953 provides Metro and Long Haul designers with
system critical features such as: low power dissipation
(1.1 W at Vo=6 V), very low rail ripple, high voltage drive
capability at 5V bias (6 V amplitude adjustable to 3 V), low
output jitter (10 ps typical), and low input drive sensitivity
(250 mV at Vo=6 V).
Primary Applications
• Mach-Zehnder Modulator Driver for
Metro and Long Haul.
Measured Performance
TGA4953 Evaluation Board (Metro MSA Conditions)
10.7 Gb/s, Vplus=5 V, Id=210 mA, (Pdc=1.1 Watt)
Vout=6 Vpp, CPC=50%, Vin = 500 mVpp
Scale: 2 V/div, 15 ps/div
The 4953 requires external DC blocks, a low frequency
choke, and control circuitry.
The TGA4953-EPU is available on an evaluation board.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.

RF SPECIFICATION
(Continued)
Notes:
1/ Verified at package level RF test.
2/ Package RF Test Bias: Vd=5 V, adjust Vg1 to achieve Id=65 mA then adjust Vg2 to achieve
Id=200mA, Vctrl=+0.2 V
3/ Verified by design, SMT assembled onto a demonstration board detailed on sheet 6.
4/ Vin=250mV, Data Rate = 10.7Gb/s, VD1=VD2T or greater, VCTRL2 and VG2 are adjusted for maximum output.
5/ Computed using RSS Method where Jrms_additive = SQRT(Jrms_out2 - Jrms_in2)
6/ Verified at die level on-wafer probe.
7/ Power Bias Die Probe: Vtee=8 V, adjust Vg to achieve Id=175 mA+/-5%, Vctrl=1.5 V
Note: At the die level, drain bias is applied thru the RF output port using a bias tee, voltage
is at the DC input to the bias tee.
Note: Devices designated as EPU are typically early in their characterization process prior to finalizing all electrical and process
specifications. Specifications are subject to change without notice.
