W3011 General Description

The W3011 1 GHz Quadrature Modulator is a monolithic integrated circuit that provides directmodulation of an RF carrier by I & Q basebandinputs. It is particularly suited for use in mobile and handheld cellular telephones designed to the IS-136 (North American 824 MHz to 849 MHz), PDC (Japan RCR-STD27 889 MHz to 958 MHz), and other digital personal-communications standards.

The circuit block diagram is shown in Figure 1. From two LO signals, LOL and LOH, the offset mixer produces an internal LO signal, which prevents the external VCOs from being pulled by the large transmitted signal. The phase shifter splits the LO signal into two carriers with 90° phase separation and equal amplitude.

These signals are fed to the in-phase (I) and quadrature-phase (Q) double-balanced mixers. The resulting signals are summed and fed into the output amplifier. This amplifier can provide 0 dBm linear output power, minimum, into a 50 load.

The output power can be attenuated up to 50 dB by applying a control voltage to the APC input. Nominally, the output power is at maximum (+3 dBm) with VAPC > 2.2 V, and at minimum (50 dBm) with VAPC < 0.8 V.

A CMOS/TTL-compatible logic input allows the device to be put into a powerdown mode in which less than 10 A of supply current is consumed.

W3011 Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, as shown in Table 2. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

W3013 General Description

The W3013 is a monolithic integrated circuit that provides indirect, quadrature modulation of an RF carrier by I & Q baseband inputs. The function performed by the W3013 is particularly suited for handheld digital cellular and digital cordless telephones that operate between 800 MHz and 2.2 GHz.

The circuit block diagram is shown below. From a single local-oscillator input (LO1), the phase shifter produces two LO signals with 90° phase separation and equal amplitude. The LO signals are fed to the in-phase (I) and quadrature (Q) double-balanced mixers. The resulting signals are summed and fed into an RF mixer where the frequency can be translated to over 2 GHz.

Outputs between the summer and RF mixer are available for external filtering. Finally, the signal is amplified to provide a single-ended output. The ENB/APC input with a logic low allows the device to be put into a powerdown mode. Above the logic low threshold, the device enters a power control mode that provides a range of desired output power levels.

W3013 Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.
