Prođuct Description


RFMD's RFSA4023 is a fully monolithic analog tempera ture. compensating attemuator (TCA) fea-turing excep tional linearity over its entire gain contro1 range. It is designed to offset the gainreduction of an RF component over temperature without the neeđ for closed loop feedback.Three cust omer selec table temperature coefficients make it a flexible solution for RF lineups.Itincorporates revolutionary new circuit architecture to solve a long stanđing industry problemwith regards to atte nuatof architecture: high IP3. low DC current anđ broad bandwidth. Tradi-tional approaches for so1ving this problem require expensive co-fired ceramics with te mpera-ture sensitive materials or current hungry PIN diodes with elaborate area consuming co ntrolcircuits. This temp erature comp ensating attenuator requires only a single supply voltage and


two logic bits to set control attenuation slope versus temperature. The RFSA4023 draws averylow 1mA current and is packaged in a smalf 3mmx3mm QFN. This attenuator is matched50 over its rated control range anđ frequency with no externa1 matchi ng c ompo nents arequired.
