Description  
Embedded integer-N synthesizer  
– Dual modulus programmable prescaler  
(16/17 or 19/20)  
– Programmable reference frequency divider  
(10 bits)  
The STMicroelectronics STW82101B is an  
integrated down converter providing 8.5 dB of  
gain, 9.5 dB NF, and a very high input linearity by  
means of its passive mixer.  
– Adjustable charge pump current  
– Digital lock detector  
– Excellent integrated phase noise  
– Fast lock time: 150 µs  
Embedding two wide band auto calibrating VCOs  
and an integer-N synthesizer, the STW82101B is  
suitable for both Rx and Tx requirements for  
Cellular infrastructure equipment.  
The integrated RF balun and internal matching  
permit direct 50 ohm single-ended interface to RF  
port. The IF output is suitable for driving 200-ohm  
impedance filters.  
Integrated DAC with dual current output  
Supply: 3.3 V and 5 V analog,  
3.3 V digital

Dual digital bus interface: SPI and I C bus (fast  
By embedding a DAC with dual current output to  
drive an external PIN diode attenuator, the  
STW82101B replaces several costly discrete  
components and offers a significant footprint  
reduction.
