LNA Boasts 20.5-dBm Gain, 0.8-dBm Noise Figure
Taking advantage of the company’s advanced, low-power SiGe BiCMOS process, the MAX2659 high-gain, low-noise amplifier (LNA) from Maxim Integrated Products achieves a 20.5-dB gain and a noise figure of 0.8 dB. The device hits these performance levels while maximizing the input-referred 1-dB compression point and third-order intercept point at -12 dBm and -2 dBm, respectively.

USB Modems Support Faster HSUPA Data Speeds
A pair of USB modems for High-Speed Uplink Packet Access (HSUPA) networks offer tri-band connectivity and faster data speeds to mobile broadband networks worldwide. Theoretically the modems more than five times that of current High-Speed Downlink Packet Access (HSDPA) networks at a maximum transmit speed of 2 Mbits/s. Downlink speeds are also improved with a theoretical maximum of 7.2 Mbits/s.

The Path To 4G Will Take Many Turns
A race is going on right now and it's a heated one. It's a race to the next generation of untethered communications—4G mobile broadband wireless. The prize for reaching the finish line first or even finishing at all could be huge. Yet that finish line keeps moving, as the fourth generation (4G) isn't yet fully defined. In fact, spectrum won't be allocated until 2007. Standards probably won't be complete until the year after that. Right now, though, many teams across the globe are...
