| Abstract: | This paper presents a highly programmable front-end filter and amplifier intended to replace SAW filters and low noise amplifiers (LNA) in multi-mode direct conversion radio receivers. The filter has a 42 MHz bandwidth, is tunable from 1850 to 2400 MHz, achieves a 5.8 dB NF, –25 dBm in-band 1-dB input compression point (ICP) and 0 dBm out-of-band ICP while drawing 26 mA from a 2.5 V supply. |
