Now available for all SATCOM bands, the 1/3 Rack BLock Up and Down Converter provides this product with the additional feature of an internal amplitude slope adjustment of 4dB nominal over a bandwidth as wide as 1GHz. The internal slope adjustment allows the user to balance the converter output to compensate for distribution & line losses subsequent to the converter. The space savings 1/3 rack size permits in a standard 1 RU rack space the configuration of a redundant block converter system using two 1/3 rack converted and a 1/3 rack NSU switch over unit. Other redundant configurations or RF & IF satcom signal distribution systems can configures in a 1 RU space using other members of the MITEQ 1/3 rack product family…
- C-, X-, Ku-, DBS, K-, & Ka- BUCs & DNCs
- Test translators for all bands

MITEQ has also introduced, and will be showing, an exceptionally low noise series of redundant Ka-band Low Noise Block Converter (LNB) assemblies covering from 17.7 to 21.2GHz in five specific bands of either a 500MHz or a 1GHz bandwidth. The noise temperature of the LNBs is typically 100 K at 21.2GHz and 110 K maximum. LNB gains of 40dB, 50dB, & 60dB are available with the 60dB model as a catalog model. The phase noise of the LNBs are superior to the phase noise specification of MIL-STD-188-164B. The plate assemblies are fully redundant; outdoor antenna mounted products, and come in the following configurations; 1:1, 1:2, & Dual 1:1. Each version is supplied with its corresponding indoor rack mount 1RU controller. Remote control via RS485 / RS 422 or optional 10/100 Base-T Ethernet is provided. Both the LNBs and power supplies are hot swappable. In addition to the Ka-band redundant LNB assembly MITEQ also supplies similar versions in C-, X-, & Ku-bands as well as redundant LNA Plate assemblies in all the satcom bands. Other redundant, outdoor antenna mount assemblies available from MITEQ are line driver amplifiers, and WS series high performance block up & down converters.
A third new offering is MITEQ’s UPC2 Uplink Power Control for critical Ka-band links, which is available with remote site diversity switching. The UPC2 can precisely adjust up to 10 independent Tx IF channels with up to 20dB of attenuation in 0.2dB steps. The UPC2 is a rack mount, 2RU, unit which is placed in series and prior to the BUC, with from 1 to 10 independent BUCs, Tx channels being controlled by one UPC2. The specific path attenuator setting is determined by the UPC2 monitoring the satellite’s beacon, provided from a separately supplied beacon receiver. The UPC2 then accurately determines the IF path attenuator value from the minimum insertion loss value up to a -20dB Tx power correction level in 0.2dB steps. The UPC2 can also directly control MITEQ WS series BUCs without using the UPC2 attenuators, thereby, eliminating the need to add attenuator options to control multiple MITEQ BUCs. The UPC2’s Site Diversity Switching Option permits communication between a local site UPC2 and a redundant remote site UPC2, which controls that sites Tx link. For example, if a deep Ka-band rain fade of 12dB occurs at the local site while the remote site is unaffected, the two UPC2s communicate via an Ethernet link—based on the user programed down link signal strength measurement redirect the redundant IF signals to the clear air, remote site so that the overall power level seen at the satellite transponders is maintained and balanced. The UPC2 has an attractive, color touch screen display for easy user interface. Remote control is available through an Ethernet interface supporting HTTP, or Telnet, or SNMPv1. Each UPC2 is equipped with fully redundant power supplies.
