Guide to Pick Right Block Up Converter

BUC stands for ‘Block Up Converter.’ Its main function is to transmit signals to satellites. Users install it to change a low IF frequency signal to higher frequencies for transmission to a satellite.

To select the most appropriate Block Up Converter, you must consider all these parameters.

  • – Input: Input in the BUC is the intermediate frequency (IF frequency), which is received by the device to be amplified and up-converted. You must check the range of frequencies it can receive these are typically L band between 950 and 2200MHz.
  • – Output: It is the frequency (RF frequency) that is sent out of the satellite after amplification. It is denoted using Frequency bands such as Ka-Band, Ku Band, C Band and X Band, etc.
  • – Gain: It is the magnitude raised by the device after amplification. Different types of BUCs have different gains.
  • – DC Voltage: It is the voltage that the device requires for operation. It is also different for different BUCs.
  • – Connector: You should also check the type of connector. There are a variety of connectors like N-Type or SMA, both Male and Female.
  • – LO Frequency: Also check the LO (Local Oscillator) frequency, because it is necessary for the transmission of the correct frequency.
  • – Grade: You should also check the grade of the device as there are commonly two grades available, Military and commercial.
