Product specification  
2 GHz image rejecting front-end  
UAA2077BM  
Image rejection is achieved in the internal architecture by  
two RF mixers in quadrature and two all-pass filters in  
I and Q IF channels that phase shift the IF by 45° and 135°  
respectively. The two phase shifted IFs are recombined  
and buffered to furnish the IF output signal.  
FEATURES  
• Low-noise, wide dynamic range amplifier  
• Very low noise figure  
• Dual balanced mixer for over 25 dB on-chip image  
rejection  
For instance, signals presented at the RF input at the  
LO + IF frequency are rejected through this signal  
processing while signals at the LO − IF frequency can form  
the IF signal. An internal switch enables the upper or lower  
image frequency to be rejected.  
• IF I/Q combiner at 188 MHz  
• On-chip quadrature network  
• Down-conversion mixer for closed-loop transmitters  
• Independent TX/RX fast ON/OFF power-down modes  
• Very small outline packaging  
The receiver section consists of a low-noise amplifier that  
drives a quadrature mixer pair. The IF amplifier has  
on-chip 45° and 135° phase shifting and a combining  
network for image rejection. The IF driver has differential  
open-collector type outputs.  
• Very small application (no image filter).  
APPLICATIONS  
The LO part consists of an internal all-pass type phase  
shifter to provide quadrature LO signals to the receive  
mixers. The centre frequency of the phase shifter is  
adjustable for maximum image rejection in a given band.  
The all-pass filters outputs are buffered before being fed to  
the receive mixers.  
• 1800 MHz front-end for DCS1800 hand-portable  
equipment  
• Compact digital mobile communication equipment  
• TDMA receivers e.g. PCS and RF-LANS.  
The transmit section consists of a low-noise amplifier and  
a down-conversion mixer. In the transmit mode an internal  
LO buffer is used to drive the transmit IF down-conversion  
mixer.  
GENERAL DESCRIPTION  
UAA2077BM contains both a receiver front-end and a high  
frequency transmit mixer intended to be used in mobile  
telephones. Designed in an advanced BiCMOS process it  
combines high performance with low power consumption  
and a high degree of integration, thus reducing external  
component costs and total front-end size.  
All RF and IF inputs or outputs are balanced.  
Pins RXON, TXON and SXON enable a selection to be  
made of whether to reject the upper or lower image  
frequency and control of the different power-down modes.  
Special care has been taken for fast power-up switching.  
The main advantage of the UAA2077BM is its ability to  
provide over 25 dB of image rejection. Consequently, the  
image filter between the LNA and the mixer is suppressed.
