In response to increased X-band communications requirements, Locus Microwave has developed a 5 or 10 W miniature Block Upconverter (BUC). The UB61000-037/-040 provides a cost-effective, compact and rugged solution for a variety of X-band communications needs including commercial, military and military Manpack SATCOM systems. This unit features an L-band interface with an X-band (7.9 to 8.4 GHz) output with power ratings at 5 or 10 W available in the same package form factor.
The Locus UB61000-037/-040 series converts the L-band (950 to 1450 MHz) input frequency range to the X-band (7.9 to 8.4 GHz) range using a phased-locked 6.95 GHz local oscillator and mixer. Amplification is provided at both the L-band frequency input range and the X-band output range. The gain for the UB61000-037/-040 is specified at 50 dB minimum and 53 dB as a typical performance featuring a flatness of ±1.25 dB maximum over the width of the full band and a slope of ±0.4 maximum per 40 MHz. This unit operates at an option of either 12 or 48 VDC. Key performance specifications are listed in Table 1; complete gain and power versus frequency is shown in Figure 1.
With military communication applications in mind the UB61000-037/-040 has phase noise (SSB) performance that exceeds the MIL-STD-188-164A specifications for performance, as illustrated in Figure 2. This unit operates in a variety of environments with ratings for temperatures spanning from -40 to +50°C as well as an environmental humidity rating of 100 percent including allowances for condensation. These specifications ensure the best possible performance for the longest duration for field communications.
The UB61000-037/-040 is packaged in a compact yet ruggedized and weather resistant housing, which is designed for both indoor and outdoor environments. Different heatsink options are available for the UB61000-037/-040 providing a variety of options for practical applications. These options affect the dimensions of the unit; however, the weight remains approximately seven pounds.
This unit is available with full thermal heatsinking creating a package that is efficient and cool, but still compact. The UB61000-037/-040 with heatsinks is competitively sized at 6 x 5.88 x 4.3 inches. This compact size is ideal for antenna mount applications.
The UB61000-037/-040 is available without thermal heatsinking as well. This option creates an extremely small package size (6 x 3.5 x 2.35 in). The advantage to this type of packaging is the ease of system integration. This unit can be integrated into systems that have pre-engineered thermal cooling considerations. An example of this is a military Manpack communications system. The UB61000-037/-040, like all Locus Microwave products, is available in variety of colors such as white, green or tan.
The Locus Microwave UB61000-037/-040 high performance miniature X-band BUC provides a cost-effective, lightweight and versatile solution for a variety of X-band communications applications. These applications include both commercial and military systems.
To supply the emerging X-band communications niche, Locus provides a full line of Block Upconverters, low noise amplifiers and solid-state power amplifiers. Additional information about the UB61000-037/-040 or any Locus Microwave product may be obtained via e-mail at firstname.lastname@example.org.
