1. DESCRIPTION
The SA2400A is a fully integrated single IC RF transceiver designed
for 2.45 GHz wireless LAN (WLAN) applications. It is a direct
conversion radio architecture that is fabricated on an advanced
30 GHz f
T
BiCMOS process. The SA2400A combines a receiver,
transmitter, and LO generation into a single IC. The receiver
consists of a low-noise amplifier, down-conversion mixers, fully
integrated channel filters, and an Automatic Gain Control (AGC) with
an on-chip closed loop. The transmitter contains power ramping,
filters, up-conversion, and pre-drivers. The LO generation is formed
by an entirely on-chip VCO and a fractional-N synthesizer.
Typical system performance parameters for the receiver are 93 dB
gain, 7.5 dB noise figure, input-referred third-order intercept point
(IIP3) of +1 dBm, AGC settling time of 8
μ
s, and Tx-to-Rx switching
time of 3
μ
s. The transmitter typical system performance parameters
are an output power range from –7 dBm to +8 dBm in 1 dB steps,
–40 dBc carrier leakage after calibration, 22 dB sideband
suppression, in-band common mode rejection of 30 dB, and
Rx-to-Tx switching time of 3
μ
s.
2. FUNCTIONAL BLOCKS AND FEATURES
The block diagram of the SA2400A Direct Conversion transceiver is
given in Figure 1. It consists of the following functional blocks:
A 79 dB adjustable gain range direct conversion zero IF receiver
with 3
μ
s (typical) Tx to Rx switching time, and comprising the
following:
– Front-end LNA with two internal gain states
– A fast on-chip closed loop composite RF and IF AGC with
zoomed analog RSSI output and 8
μ
s settling time
– Quadrature downconverters from 2.45 GHz RF directly to
zero IF
– On-chip fast baseband DC cancellation with automatically
stepped bandwidths of 10 MHz, 1 MHz, 100 kHz, and 10 kHz,
settling within 8–13
μ
s for a DC error of 10% that decays to 1%.
– Fully integrated channel filters, appropriate for 11 Msymbols/s
QPSK modulation RF bandwidth.
An I/Q upconverter from baseband directly to 2.45 GHz, with
+8 dBm output power, –40 dBc typical carrier leakage (calibrated)
and 3
μ
s (typical) Rx to Tx switching time, and comprising the
following:
– Wide band IQ modulator producing better than 14% EVM for
11 Msymbols/s QPSK modulation
– Integrated reconstruction and spectral shaping filters at I and Q
modulation input that is driven by an external D/A. High
common mode rejection to input ground bounce.
– FIR-DACs for digital I/Q input feeding the analog signal path
and including additional filtering for spectral shaping.
– 2.45 GHz power amplifier driver with +8 dBm maximum output,
15 dB adjustable gain in 1 dB steps and a second switched
output at –1.5 dBm power level with similar gain adjustments
that are set by a separate register.
– Completely on-chip calibration for Carrier Leakage
compensation.
– Internal power ramping with 2
μ
s delay and 0.5
μ
s ramp-up
time.
A fractional-N frequency synthesizer with on-chip VCO and XO
A 3-wire bus for control of most blocks
An additional high speed 3-wire bus for full control of Rx-Gain and
DC-offset compensation parameters with 44Mbits/s.
Fast Tx-Rx switching based on a single digital input pin.
Reference currents and voltage for supply of Baseband Processor
and PA-chip.
