COMPONENTS / SUBSYSTEMS NEW PRODUCTS & SERVICES Duplexers and Diplexers for all Major LTE Bands and Small Cell Power Levels CTS Corp. has introduced three new product families of ceramic monoblock duplexers and a family of diplexer filters. Each family offers a single universal printed circuit board footprint that supports all of the major cellular frequency bands. The Universal Metro-Cell Duplexers (UMD), Universal Small-Cell Duplexers (USD), Universal Pico-Cell Duplexers (UPD) and high-performance universal Diplexers (DPX) filters are designed to provide the power handling and performance requirements of LTE infrastructure systems. The CTS UPD are 44 mm long monoblock duplexers that provide the required levels of rejection, insertion loss, peak power handling and reliability for carrier-grade multi-band Pico Cells with linearized power amplifiers that cannot be met by SAW, BAW or FBAR filters. These duplexers deliver 61 dB of rejection with insertion loss of less than 3.0 dB. The input power rating of 1.5 watt average and 15 watt peak is suitable for systems of 24 dBm and 27 dBm RF power at the antenna port. The USD duplexers are 63 mm long monoblock duplexers offering improved performance for indoor and outdoor small-cell and low-power per element active antenna arrays. These filters are also suited for whole-band indoor DAS or carrier-aggregation systems of 0.25 watt at the antenna where additional rejection is required. These duplexers deliver 71dB of rejection with less than 2.6 dB of worst case insertion loss. These are rated for input power handing up to 6 watt average and 60 watt peak. The UMD duplexers are constructed as a match pair of 62 mm long bandpass filters, precisely designed for outdoor metro-cell, active antenna arrays, remote radio head and other applications supporting 4 to 10 watt at the antenna. They are also essential for whole-band, distributed antenna systems (DAS) or carrieraggregation systems for 1 watt at the antenna where additional rejection is required. These duplexers deliver 80 dB of rejection with less than 2.2 dB of worst case insertion loss and are rated for input power levels up to 20 watt average and 200 watt peak. The CTS duplexers and diplexers are operable at temperature ranging from -40°C to 85°C and all have a return loss of at least 12 dB worst case. Most importantly, they address all of the major LTE bands, including the most challenging ones and all with a common PCB footprint. Cree Releases New 50 Volt Broadband GaN HEMT Cree, Inc. has extended its family of 50 V gallium nitride (GaN) high electron mobility transistors (HEMTs) with a new 50 W packaged part that provides high performance broadband solutions for a variety of RF and microwave applications up to 4 GHz, including narrow band UHF applications, L- and S-Band applications, and multi-octave bandwidth amplifiers. Available in two-leaded flange and pill packages, the CGHV40050 exhibits high efficiency, high gain, and wide bandwidth performance, all of which can be demonstrated using the a 0.8 to 2.0 GHz high power amplifier (HPA) reference design included in the datasheet, in addition to high power density and low parasitics. Delivering 50 W typical output power up to 4 GHz operation, the CGHV40050 typically provides 17.5 dB small signal gain at 1.8 GHz and 55 percent efficiency at PSAT, and is rated for an operating junction temperature (TJ) of 225°C, and case operating temperatures (TC) spanning -40°C to 80°C. www.AntennasOnline.com Summer 2015 Antenna Systems & Technology 19 http://www.AntennasOnline.com
