Low voltage dual-band RF front-end
Product specification
SA3600
DESCRIPTION
The SA3600 is an integrated dual-band RF front-end that operates at
both cellular (AMPS and TDMA) and PCS (TDMA) frequencies, and
is designed in a 20 GHz f_T BiCMOS process—QUBiC2.
The low-band (LB) receiver is a combined low-noise amplifier (LNA)
and mixer. The LNA has a 1.7 dB noise figure (NF) at 881 MHz with
17 dB of gain and an IIP3 of –7 dBm. The wide-dynamic range mixer
has a 9.5 dB NF at 881 MHz with 9.5 dB of gain and an IIP3 of
+6 dBm.
The high-band (HB) receiver is a combined low-noise amplifier (LNA)
and mixer, with the low-band and high-band mixers sharing the same
mixer output. The LNA has a 2.2 dB NF at 1960 MHz with 16 dB of
gain and an IIP3 of –5 dBm. The wide-dynamic range mixer has a 8.5
dB NF at 1960 MHz with 8.5 dB of gain and an IIP3 of +5.5 dBm.
FEATURES
• Low current consumption: LB I_CC = 14.5 mA; HB I_CC = 20.5 mA
• Outstanding low- and high-band noise figure
• LNAs with gain control (30 dB gain step)
• LO input and output buffers
• Selectable frequency doubler
• On chip logic for network selection and power down
• Very small outline package
APPLICATIONS
• 800 to 1000 MHz analog and digital receivers
• 1800 to 2000 MHz digital receivers
• Portable radios
• Mobile communications equipment
