Automated RF Component Assembly Cell

August 30, 2001 9:29 am | Comments

Palomar Technologies, an innovator in high-precision automated assembly systems for broadband communications, introduces the HotRail™ RFA (Radio Frequency Assembly) Cell for automated assembly of RF power amplifier components. The new automation system lowers the cost of production for power amplifiers used in wireless base stations, ultimately helping wireless carriers lower their costs to subscribers....

Ferrite Chip and Power Beads

August 30, 2001 9:29 am | Comments

Spectrum Control introduces the newest addition to its SPECWAVE line of wireless components. Spectrum's ferrite chip beads (FCB) and ferrite power beads (FPB) offer design flexibility through standard EIA/EIAJ sizes in a wide array of electrical values for EMI attenuation applications. These ferrite chip and power beads provide EMI attenuation while eliminating the need for grounding, and the multilayer construction provides a closed magnet...

Leaded and Chip Ceramic Resonators

August 30, 2001 9:29 am | Comments

Leaded and chip surface-mounted ceramic resonators are now available from Spectrum Control. The leaded ceramic resonators feature a built-in load capacitance. This feature eliminates the need for external load capacitors necessary for traditional filter design. No adjustment is necessary after completion of the circuit; the oscillator will perform at the originally designed frequency....

Surface Mount Chip Resistor

August 30, 2001 9:28 am | Comments

Providing design engineers with a space-saving alternative to bulky wirewounds, IRC has developed a series of surface mount resistors available in standard and non-standard values capable of dissipating up to 3 watts at 70°C. Designated the SC3 Series, these thick-film resistors are less inductive than typical wirewound devices and require 75 percent less board space....

Batteries

August 30, 2001 9:28 am | Comments

The newest addition to the EnerSys line of Phoenix batteries increases performance up to 8% at the 15 minute rate over batteries with the same footprint. The PHX12-475, a valve regulated Lead-Tin battery designed for high rate applications, uses absorbent glass mat (AGM) technology to retain acid between plates and enhance battery cyclability during normal UPS operation....

Cellular Band VSWR Monitor

August 30, 2001 9:28 am | Comments

Narda's low-cost VSWR monitor provides an ideal solution for service providers who only need a Form-C relay closure when a Tx VSWR failure occurs. Model 8460LP-N2 operates from 869 to 994 MHz. It samples the forward and reverse power and calculates the VSWR through a high directivity coupler. Forward and reverse sampling ports are also provided....
