FPGAs Welcome Latest Wireless Applications
Wireless engineers are increasingly relying on field-programmable gate arrays (FPGAs) for their advantages in terms of power, functionality, and cost. FPGAs are particularly suitable for emerging wireless applications, which must satisfy ...
Services Prey On Location
PASN will enhance social-networking applications by allowing users to easily find and connect with one another.
PXI RF Switches Beat 2.1 dB Insertion Loss
To help engineers optimize their RF switch networks, 11 PXI RF switches have been spawned. The modules, which target 50- and 75-Ω RF applications, include 4 X 1, terminated 4 X 1, dual 4 X 1, and 8 X 1 multiplexers as well as quad single-pole, ...
Tiny Chip Baluns Cut Insertion Loss To 0.6 dB
Multilayer chip baluns have emerged to tackle the impedance matching between equilibrium/nonequilibrium circuits in RF circuits for WiMAX communications equipment. At 1.6 X 0.8 X 0.6 mm, these multilayer baluns boast an insertion loss of 0.6 dB ...
Phased-Array-Antenna Transceiver System Spans 10 To 35 GHz
Both commercial and military wireless-communication applications require systems that can operate over multi-frequency bands. Although a wideband phased-array antenna transceiver system has been looked at as a potential solution, its bandwidth ...
Linear Amplifier Boasts 80 W Output Power
By providing wideband operation in a compact and lightweight form, a solid-state Class AB linear power amplifier (PA) satisfies a variety of military needs. The model BM2719-80-3, which spans 20 to 1000 MHz, boasts RF output power of 80 W. Its ...
Interconnect Techniques Reside On One Substrate
A new etchable materials capability is promising to allow circuit designers to integrate more functions and improve performance while reducing package size. Specifically, the advanced PCTF technology enables designers to combine a number of ceramic ...
Electronic Line Stretchers Simplify VCO Measurements
Voltage-controlled oscillators (VCOs) are usually designed to operate in an ideal 50-Ω environment. These oscillators often have to drive a much different load, however. When the VCO output encounters a load with 12-dB return loss for all ...
Monopole Antenna Satisfies 5.8-GHz RFID Applications
Radio-frequency-identification (RFID) systems comprise a read/write device, such as a tag, and a transponder. Because it is attached to the object to be identified, the tag must maintain a very low profile while satisfying demands for low cost ...
PIN Diodes Handle 100 W CW RF Power
A new family of non-magnetic, metal-electrode-leadless-faced (MELF) -packaged PIN diodes features high power handling and low distortion. At 100 mA, the product family has a resistance specification at 100 MHz from 0.3 to 1.0 Ω. Its capacitance ...
