China Explores Small Cells’ Potential
As China Mobile continues to roll out TD-SCDMA and TD-LTE networks, it faces some of the same coverage gaps encountered elsewhere in the world: spotty indoor coverage, insufficient capacity for crowded public places, and more.
Spectrum-Shortage Outlook Is Grim
According to CTIA-The Wireless Association (
www.ctia.org), the US government controls 409.5 MHz of spectrum for commercial wireless services—although not all of that bandwidth is at ideal frequencies. The frequency range best suited for high-speed, commercial wireless-broadband services is between 400 MHz and 3 GHz.

Clock-Divider IC Has Delay Adjustment
Designed for outstanding phase-noise performance, model HMC988LP3E is a clock divider and delay management IC that can handle clock signals as high as 4 GHz, dividing them by ratios of 1, 2, 3, 4, 8, 16, or 32.
Phase Shifter Runs 9 To 11 GHz
Designed for applications from 9 to 11 GHz, model PS-9G11G-3609-A-SFF is an analog phase shifter that can control a phase-shift range of 0 to 360 deg. It uses a phase-shift control voltage from -7.5 to +7.5 VDC.
Diplexer Passes 3.5 and 5.5 GHz
Suitable for combining or separating WiFi and WiMAX signals in the 2.4- and 5-GHz bands, the model BK-28N diplexer has passbands of 2.400 to 3.800 GHz and 5.150 to 5.850 GHz.
Flat-Panel Antenna Combines Polarizations
The HyperLink HG2414DP-3NP flat-panel antenna is designed for multiple-input, multiple-output (MIMO) point-to-point and point-to-multipoint applications in the 2.4-GHz frequency band.
LDMOS Device Delivers 1 kW
Model PTVA101K02EV is a high-power silicon RF LDMOS field-effect transistor (FET) designed for use in power amplifiers operating in the frequency range from 1030 to 1090 MHz.
GaN Powers 10-W Amplifiers
The NuPower™ line of L- and S-band solid-state power amplifiers is ideal for unmanned aerial vehicles (UAVs) and unmanned aircraft systems (UAS) applications, as well as for broadband telemetry and communications.
Make Sense Of Sensing
When emerging opportunities in the microwave and general electronics market are brought up, sensing is often mentioned. Already, touchscreens and accelerometers have seen vastly increased adoption in mobile phones.
Software Speeds PA Design
In RF and microwave engineering, the design and development of power amplifiers (PAs) is something of a black art. In addition to years of focused engineering experience, it demands a suitable collection of test and measurement equipment.
