The RF front-end complexity in 4G multimode multiband cellular radios has increased dramatically, requiring integration of PAs, filters and switches in a single module to reduce the RF footprint. This paper presents a fully integrated multimode TDD transmit front-end module (TXM) supporting GSM/EDGE/TD-SCDMA/TD-LTE in multiple bands. The TXM is implemented with three die on a 2-layer laminate LGA...
This paper presents a 55nm 4-in-1 (11b/g/n, BT, FM, and GPS) radio assembled side-by-side with a 3-metal layer integrated-passive-device (IPD) chip in a QFN40 package. One 2.4GHz transceiver is area-efficiently shared between WiFi and Bluetooth systems. Including a 3dB IPD insertion loss, at chip output (antenna port) the saturated output power of the 11bgn integrated PA is 25dBm; the receiver noise...
For a highly integrated wireless system including on-chip antennas, high-output-power power amplifiers (PA) are required to cover the desired transmission range. In order to achieve the output power level, power-combining techniques have gained more attention in recent years [1–5]. An efficient power-combining solution is essential since less DC power is needed for the same level of output power,...
A 77 GHz fully-integrated power amplifier (PA) with 50 Ω input and output matching has been realized in a general purpose 90 nm CMOS technology. In order to improve the output power and reduce the signal loss, a transformer and a short stub topology are employed respectively. The power amplifier achieves a saturated output power (Pout,sat) of +13.2 dBm and 1dB compressed output power (Pout,1dB) of...
