SOLE SOURCE JUSTIFICATION / BRAND NAME SPECIFICATION

Direct Drive Power Amplifier Fabrication

BACKGROUND:

Naval Undersea Warfare Center Division, Newport (NUWCDIVNPT) is conducting a Technology Refresh on the AN/WSQ 9 Signal Analysis System. A new conformal array concept is being developed which has a significantly smaller package size. A new power amplifier needs to be designed since existing power amplifiers cannot be packaged into the conformal array housing. QorTek, Inc. conducted a trade study on a prior contract showing a direct drive power amplifier using their patented technology achieves a compact power amplifier that can be packaged in a conformal array. TQ Electronics, Inc. is licensed by Qortek, Inc. to fabricate direct drive power amplifiers using Qortek’s patented direct drive power amplifier technology.

REQUIREMENT:

NUWC Division Newport requires a direct drive power amplifier be developed to drive the array elements of the conformal array that can be for packaged in a 1 ½” cylinder with height of 3 inches. In order to achieve this packaging constraint, the new power amplifier design must have no magnetics in the output stage for voltage step-up or impedance tuning. The output semiconductors must drive the array elements directly.

SOLE SOURCE JUSTIFICATION/BRAND NAME SPECIFICATION:

TQ Electronics is the only company licensed to fabricate Qortek’s direct drive power amplifier technology. TQ Electronics will use Qortek’s patents for high power density direct drive power amplifiers: “High Frequency Switch Circuit” 7,330,055 B2, “Gate Drive Circuit with Negative Offset” 7,170,321 B2, “Reduced Component Drive Circuit”, 6,720,706 B2 and Device and Method for Driving Symmetric Load Systems” 6,465,931 B2. These patents are used in the direct drive power amplifier which enables packaging of the power amplifier in a small package, which is required for this development. With the requirements of the power amplifier to be physically small, TQ Electronics is the only manufacturer for fabrication of direct drive power amplifiers.

RESELLERS:

There are no authorized resellers. The Direct Drive Power Amplifier Technology is a proprietary product of Qortek which is licensed to TQ Electronics.

Requiring Department:

Based on the above, I recommend this acquisition be conducted on a Sole Source/Brand Name Specification basis. I certify the technical data which form the basis of this justification are complete and accurate.
