OEM Linearizer Modules

Tri - Band

The BAFL 8000E linearizer module is designed as an economical solution to the problem of linearizing tri-band TWTAs at X-band. It provides both enhanced multi-carrier intermodulation performance and reduces spectral regrowth. The BAFL-8000E is pre-aligned and requires a minimum of tuning at installation.

Tri-Band TWT Linearizer Modules

Ku & DBS (K - Band): BAFL-14000/18000

The BAFL 14000 and 18000 series predistortion linearizer modules are intended to be installed within TWT and Klystron high power amplifiers. They are compact and feature analog or digital control. They typically give a 4X power increase with multicarrier traffic and advanced digital modulation. Alignment is done at the time of installation and typically requires less than 10 minutes.

BLFE Series

Compact Digitally Controlled Linearizer Modules for Use in TWTAs Power Amplifiers

The BLFE-6000S/8000S/14000S/18000S/28000S/45000S series offer a complete frontend and a predistortion linearizer in a single compact module.  They are intended to be installed within TWT and Klystron high power amplifiers.  SSPA versions are also available.  They provide high gain (>40 dB) with a wide range attenuator (>30 dB), analog or digital control, and optional power detection and mute control. They typically give a 4X power increase with multicarrier traffic and advanced digital modulation. Alignment is done at the time of installation and typically requires less than 10 minutes.

LBUCs, linearized block upconverters, are available for X, Ku and Ka and Q-band. They directly drive high power amplifiers (TWTAs, KPAs, SSPAs) from an L or X-Band signal source.  LBUCs provide high gain (>40 dB) with a wide range attenuator (>35 dB), analog or digital control, and an external or internal reference.  They typically give a 4X power increase with multicarrier traffic and advanced digital modulation. Alignment is done at the time of installation and typically requires less than 10 minutes.

PD: Custom Hybrid

Predistortion Linearizer Modules for Solid State Power Amplifiers

Available for VHF, UHF, and Microwave Millimeter Wave Bands

For Bipolar, FET, MESFET, HEMT, and HBT Amplifiers

100% support from development through production including customer product support

Class A, AB, and B Applications

A custom development program designed specifically for manufacturers of SSPAs (Solid State Power Amplifiers). It has the following steps:

1.

The amplifer manufacturer (AM) provides LTI detailed information on the non-linear characteristics of their amplifer. LTI engineers, using proprietary modeling software, will provide an estimate of the performance improvement of a custom designed LTI linearizer module. Typically, the more non-linear the amplifier, the greater the benefit of linearization.

2.

LTI will develop a breadboard module for the AM to test with their SSPA. LTI will work with the AM to optimize the module design.

3.

When an optimum design is reached, LTI will produce a hybrid preproduction engineering model for further testing to finalize the design.

4.

LTI will then finalize the production design and undertake to produce a quantity of units.
