Analogue, Mixed Signal, LSI
The LT5557, a new high linearity, 3,3 V downconverting active RF mixer from Linear Technology, elevates receiver dynamic range performance while extending bandwidth capability to cover 3G and WiMAX basestation frequencies to 3,8 GHz. The LT5557 offers 24,7 dBm IIP3, noise figure of 11,7 dB, and 2,9 dB of gain at 1,95 GHz. Its performance remains robust at WiMAX frequencies with 23,5 dBm IIP3, and 1,7 dB of gain at 3,6GHz. This performance is achieved with a low -3 dBm LO input drive level. Typical LO-to-RF isolation is better than 42 dBc at 1,95 GHz. The device's power consumption is low for this class of high linearity mixers, typically 270 mW from a 3,3 V supply. The device incorporates on-chip RF balun transformers to enable convenient single-ended, 50 Ω matching at the RF and LO inputs. It incorporates a double-balanced active mixer core topology with on-chip LO buffer. The device's wide operating bandwidth covers the 850-965 MHz GSM bands, as well as 1,7 GHz to 2,1 GHz 3G wireless services.
