SE7051L10
200 – 600 MHz Transceiver with Dual Synthesizer
Applications
802.16, WiMAX
Wireless Local Loop
Proprietary Broadband Wireless Access Systems
Product Description
The SE7051L10 is a highly integrated low noise, high
linearity transceiver that includes both RF (2850 to 3350
MHz) and IF (200 to 600 MHz) synthesizers. The
receiver down-converts signals in the frequency range
of 200 to 600 MHz to either baseband IQ outputs or IF
output. The high linearity output provides excellent
inter-modulation performance and drive capability for
the ADC interface. A high-speed digital VGA delivers
50dB of gain control range, with 1 dB resolution. On
transmit, the baseband IQ input signals are up-
converted to an IF output frequency between 200 and
600 MHz.
Alternatively, the transmitter may be
configured for single sideband up-conversion of an IF
input signal.
The transmitter has a total of 68 dB of gain control
range, with 1 dB resolution, that is distributed between
the modulator and VGA. The VGA has 50 dB range
while the modulator provides 18 dB with coarse (6 dB)
resolution. The variable gain modulator can accept a
wide range of input voltages thus allowing flexibility in
the choice of baseband DAC. The dual synthesizers
provide very low phase noise LOs that are suitable for
high order digital modulation radios.
