Description

Comtech 125W KU-Band BUC We have just received and tested this used KU-Band BUC. Lets start out with the disadvantages, it won’t win any beauty contests. This amplifier has been working on top of an SNG truck for all of its life, the only reason we have it was because the truck is being used for another project.

The model number is LPK0-31 it has standard KU Band of 14 to 14.5 GHz.

Now for the good news, we tested it with a CW to a clean 98 watt output, and it comes with the power cable and the M&C cable.

It does not need DC voltage nor the 10 MHz reference. You can see the results of the test in the downloads tab.

i never knew what LPOD stood for until I found this brief description.

The Comtech EF Data LPOD (Low Profile Outdoor Device) family includes various models designed for satellite communications. Let’s explore the Comtech EF Data LPOD C-, X-, or Ku-Band Block Up Converter (BUC)/SSPA (model LPK0-31):

1. Purpose and Overview:
   • The LPOD series is designed for both fixed and mobile satellite communications.
   • It efficiently integrates the BUC (Block Upconverter) and SSPA (Solid-State Power Amplifier) in a compact, outdoor package.
   • The LPK0-31 specifically operates in C-, X-, or Ku-Band frequencies.
2. Key Features:
   • Frequency Range:
     • C-Band: 950 – 1525 MHz
     • X-Band: 5.850 – 6.425 GHz
     • Ku-Band: 950 – 1750 MHz
   • Output Power: Not specified in the available data.
   • Compact Design: Designed to meet space and weight limitations.
   • Redundancy Options: Offers cost-effective solutions for 1:1 redundant TX and 1:1 redundant RX requirements.
   • Integrated Power Supply: Self-contained power supply eliminates the need for the modem to supply BUC voltage via the RF cable.
   • Data Logging Capability: Built-in data logging records critical operational parameters for system maintainability.
   • Advanced FSK: When used with compatible modems, it provides additional functionality for control without additional cabling.
3. Additional Specifications (from available data):
   • Input Power Supply Requirements: 90 – 264 VAC, 47-63 Hz, Power Factor Corrected (48 VDC optional).
   • 3rd Order Intermodulation Level: -30 dBc typical, -25 dBc guaranteed.
   • Operating Temperature: -40°C to +70°C.
