MGCT03

Transmit Circuit for TDMA/AMPS

DS5418

ISSUE 1.0

December 2000

Ordering Information

MGCT03/KG/QP1S

MGCT03/KG/QP1T

The MGCT03 circuit is designed for use in dual

band, dual mode cellular 900MHz/PCS1900MHz

mobile phones. It can be used for TDMA/AMPS. The

MGCT03 is compatible with baseband and mixed

signal interface circuits from Zarlink Semiconductor

and other manufacturers.

System costs have been kept to a minimum by

removing the requirement for an additional SAW ﬁlter

in the transmit IF path. The AGC has been split

between RF and IF sections to reduce noise and a

low pass ﬁlter has been included before the IF

variable gain ampliﬁer to remove spurious products

produced in the modulator.

For CDMA systems the MGCT04 is recommended.
