High-gain Amplifiers

Pasternack Enterprises has launched a family of coaxial X band high gain power amplifiers. These RF amplifiers are typically used as driver amplifiers or high power output amplifiers in a wide variety of commercial, industrial and military applications including telecom infrastructure, test instrumentation, fixed microwave backhaul, radar systems, communication systems, satellite communications and commercial avionics.

X-Band-High-Gain-Power-Amplifiers-SQ (3)X band power amplifiers are packaged inside hermetically-sealed metal enclosures and exhibit high gain, gain flatness, high linearity and wide dynamic range. This excellent performance is achieved by using a hybrid microwave integrated circuit design and advanced GaAs pHEMT technology. The connector-ized SMA amplifier modules are unconditionally stable and include built-in voltage regulation, bias sequencing, and reverse bias protection for added reliability. The power amplifier over-voltage protection is installed externally for easy repair. The RF amplifiers are fully matched internally for 50 Ohm input and output, which eliminates the customers need for any additional sensitive external RF tuning components.

The X band high gain power amplifiers are suited for high linearity applications with frequencies ranging from 8 GHz to 12 GHz. These X-band amplifiers offer 30 dB to 41 dB small signal gain over a temperature range of -30 degrees C and +70 degrees C. The gain flatness of these high gain amplifiers ranges from 0.50 dB to 1.0 dB and the IP3 output performs up to 44 dBm. The RF amplifiers are offered in 1 Watt and 4 Watt designs depending on the configuration. www.pasternack.com

RF Power Tappers

Pasternack Enterprises has launched a line of RF tappers. These low-loss power tappers (also known as signal tappers, signal samplers, equal/unequal power splitters or dividers) are used to either evenly or unevenly sample or split RF signals in LTE, Tetra, private mobile radio, UMTS or Wi-Fi systems for in-building and outdoor DAS applications.

Pasternack is offering three designs of RF tappers including two-way, three-way and four-way body styles and are available with Type-N or 7/16 DIN connectors. Equal and unequal split tappers utilize a ruggedized sealed construction, using an air dielectric structure without solder joints and have connectors with O-rings for IP65/67 required installations. Unequal signal tappers from Pasternack are available in a variety of split ratios from 2:1 to 1000:1 (4.8dB to 30dB) and operate from 376 MHz to 6 GHz. The company’s equal split tappers provide excellent performance across wireless bands from 376 MHz to 2.7 GHz, making them an ideal solution for in-building DAS.

The RF power tappers permit continuous direct current through the main line while passing RF power with minimal ripple and insertion loss. The low-PIM signal tappers have a max power rating up to 700 Watts and are designed to assist in cell phone and radio installations operating in frequency bands such as LTE, Tetra, PMR and Wi-Fi. The RF power dividers are IP65 / IP67 and RoHS compliant. www.pasternack.com

 

Armored RF Coaxial Test Cables

Pasternack Enterprises has introduced a line of flexible, armored SMA and Type-N test cables, designed to handle harsh industrial environments common in production test systems and antenna ranges. Pasternack’s armored test cables utilize stainless steel connector construction, with the SMA designed to operate to 20 GHz and the N connector to 18 GHz. These RF test cables from Pasternack are available with in-series configurations only.  A mechanical connector/armoring interface and strain relief boot increases the overall durability and life of the test cable. The company’s armored test cables are built using PE-P142LL coaxial cable which is triple shielded with an expanded PTFE dielectric, guaranteeing low loss performance.

These SMA and N-Type armored test cables are manufactured with a flexible, but rugged stainless steel armoring, which allows RF signal integrity during test, even when exposed to high traffic production environments.  The armored test cables from Pasternack are available in standard and metric lengths www.pasternack.com

High Frequency Power Dividers

Ultra-broadband two-way power dividers up to 50 GHz are available from Pasternack Enterprises. The millimeter wave power dividers (also referred to as RF power splitters) used in fiber optic systems. Configurations of broadband power dividers include two with 2.92mm connectors, one of which is a low VSWR version. Both 2.92mm power dividers are capable of frequencies ranging from 10 GHz to 40 GHz and are rated to 10 watts maximum input power. The third option is a 2.4mm power divider capable of 10 GHz to 50 GHz and also has a power rating of 10 watts. All three, high-frequency power dividers are Wilkinson two-way designs utilizing a compact package that offers low insertion loss and phase stability across their broad operating range. The 40 GHz and 50 GHz power dividers have a maximum insertion loss of 1.5 dB and VSWR of 1.6. These ultra-broadband power dividers have a typical phase balance of 6 degrees and carry a maximum isolation rating of 15 dB. Each of the 2-way RF power dividers are RoHS compliant. www.pasternack.com

Semi-Flexible Precision Cable Assemblies

Hand-formable semi-rigid RF cable assemblies up to 18 GHz, now available from Pasternack Enterprises, are an alternative to more expensive preformed coaxial assemblies. These formable semi-rigid cables are dimensionally and electrically similar to their semi-rigid counterpart and have a tinned-copper-braid outer shield that provides RF shielding, greater than 100 dB. The hand-formable cable assemblies do not require special tooling to shape or reshape the assemblies and can be formed more than once without damaging the outer conductor. The assemblies are 100 percent Hi-Pot, continuity, and 100 percent VSWR tested to the maximum frequency of assembly. www.pasternack.com
