NEC has come up with a reconfigurable analogue baseband IC for Software Defined Radio (SDR), achieved by the development of a pulse-width controlled reconfigurable filter for changing filter type ...

Digital or vector modulation can provide increased spectral efficiency, higher data security, and higher quality communications. This comes at a cost of increased system complexity and a resultant ...

The air-interface of a multi-standard receiver can be described by Figure 1. The RF input covers a wide range of RF frequency bands. Each standard has its own RF band and channel spacing. In this ...

Apair of 2.4-GHz transceivers from Maxim Integrated Products exemplifies state-of-theart design reuse in RF ICs. These zero-IF, RF transceiver chips both provide an RF-to-baseband receive path, ...

A family of five single and dual low-pass active filter/analog-to-digital converter (ADC) driver amplifier devices from Linear Technology Corp. provides high performance and wide bandwidths. A family ...
