A number of standards have sprung up in the 57-to-64-GHz band, such as IEEE 802.15.3c, IEEE 802.11ad, and WirelessHD. No matter the standard, they all have one common goal: to speed the realization of integrated circuits (ICs) that can support large wireless data transfers at those millimeter-wave frequencies.
In the area of implanted medical devices, antenna-enabled biotelemetry is gaining attention for its potential to overcome the limitations of inductive biotelemetry. Such issues include low data rate, restricted communication range, and sensitivity to inter-coil misalignment.
A family of Ka-band GaAs chipsets has been developed by TriQuint Semiconductor for use in very-small-aperture-terminal (VSAT) satellite communications systems. The family includes a variable-gain amplifier, a 1-W power amplifier (PA), a subharmonic frequency upconverter, and a block frequency downconverter.
Model XX1010-QT is a GaAs monolithic-microwave-integrated-circuit (MMIC) frequency doubler from M/A-COM Technology Solutions that is well suited for satellite-communications (satcom) and point-to-point communications systems.
A near-field communications (NFC) antenna enables mobile telephones to read data from a source at distances to 40 mm. The antenna sends and receives clear signals even when installed in close proximity to a battery or metal housing.
Model XTS-40KHE-B1 is a Ku-band block upconverter (BUC) that includes temperature compensation, gain control, harmonic filtering, receive-band filtering, and an output isolator in a compact unit weighing less than 10 lbs; it measures just 11.2 x 4.4 x 54. in.
Model P2T-14D415D4-15-SMT-20W is a driverless high-power single-pole, double-throw (SPDT) switch designed for applications from 14.4 to 15.4 GHz. It exhibits maximum insertion loss of 1.2 dB at room temperature (+25°C).
Model USSP1217-LF is a RoHS-compliant voltage-controlled oscillator (VCO) designed for L-band applications from 1210 to 1230 MHz. It tunes with voltages from 0.5 to 3.0 VDC and tuning linearity of better than 1.1:1.
Imagine that a new antenna technology truly made “broadband everywhere” possible. As the most recent spinout from Intellectual Ventures (IV), Kymeta just closed a $12-million funding round to develop and bring to market IV’s Metamaterials Surface Antenna Technology (MSA-T).
Using evolved Multimedia Broadcast Multicast Service (eMBMS) technology, it is possible for Long-Term-Evolution (LTE) network infrastructure to be used for the delivery of broadcast services, such as television. This capability, if utilized, could certainly impact how LTE services are offered.
For wireless communications that use time-division-duplex (TDD) signaling, it is very difficult to maintain synchronization. In addition to providing real-time services, base stations must maintain accurate relative timing for successful call-signal handoff.
GaN Roundtable: The State of GaN Reliability Today
Wednesday, April 3rd, 2013, 2:00 pm ET. Gallium nitride (GaN) has come a long way over the past few years in terms of affordability, industry acceptance and, in particular, reliability. In this webcast roundtable, a panel of expert speakers will assess the current state of GaN reliability, along with offering predictions for its future.
