2.4GHZ-2.5GHZ SINGLE-CHIP RF TRANSCEIVER
S1T8536
INTRODUCTION
The S1T8536 is a single chip RF transceiver optimized for use in ISM
48−LQFP−0707
2.45GHz wireless systems. It is fabricated using Samsung’s ASP5HB
0.5um advanced BiCMOS process.
The S1T8536 contains receiver, transmitter, frequency doubler,
voltage controlled oscillator (VCO), phase locked loop(PLL) and
crystal oscillator.
The receiver consists of a 2.4 - 2.5GHz high frequency mixer, an
intermediate frequency (IF) amplifier, a FM quadrature demodulator, a
received signal strength indicator (RSSI), a baseband filter buffer
amplifier and a high speed data slicer with sample & hold function.
The transmitter consists of 2.4 - 2.5GHz high frequency buffer
amplifier.
The PLL operates upto 1.3GHz with 32/33 prescaler and selectable charge pump current. S1T8536 contains on-
chip PLL regulator to minimize switching noise.
The VCO operates 1.15 - 1.3GHz and requires only external tank circuit and loop filter.
S1T8536 contains on-chip VCO regulator to minimize VCO frequency variation due to supply pushing.
The frequency doubler receives 1.15 - 1.3GHz signal from VCO and outputs 2.3 - 2.6GHz signal to receiver and
transmitter.
The crystal oscillator operates 5 - 40MHz and can accept external clock signal.
Two additional voltage regulators provide a stable supply source to external discrete stages in the Rx and Tx
chains.
