A base station is generally made up of a high power amplifier (HPA), low noise amplifier (LNA), modem, multiplexor, and up- and down-converters. In digital data transmission, data streams are combined in a multiplexing device, whose output goes to a modem for modulation onto a carrier frequency in the 50 to 180MHz range. An up-converter bumps the carrier up into the gigaHertz range, and the output goes to the HPA and dish.

Component Highlights

* PA Loop Control - solutions offer faster PA control using temperature compensation and pre-bias voltage.
* D/A Converters - interface with microprocessors and TTL logic; these DACs are optimized for high-resolution, high sampling rate, wide dynamic range, and compact size.
* LDOs, Buck switching regulators - specifically designed for noise-critical, battery-powered applications such as base stations.
* Ethernet PHY - small size, low power, fully interoperable Ethernet PHY delivers up to 1 Gbps performance.
* Select from several hardware monitors, RDTS 2-wire serial temperature sensors and SPI/Microwire compatible digital sensors.
