Features * * * * * * Active Mixer with Conversion Gain Integrated LO and IF Drivers Excellent Linearity Broadband 50 W Impedance on all Ports Low LO-RF Leakage Differential or Single Ended Inputs Benefits * Small and Thin 16-pin SSOP Package with Exposed Paddle * Few External Components * Fully ESD Protected Application * UMTS/W-CDMA and ISM Band Transmitter * Other digital Communication Applications * High Performance RF Instrumentation High Linearity Active Transmit Mixer for 2100 MHz to 2500 MHz ATR0787 Description The ATR0787 is a high linearity active mixer which is manufactured using Atmels advanced Silicon Germanium technology for the use in a variety of high performance requiring RF systems such as digital communications. This mixer features a frequency range of 2100 MHz to 2500 MHz. It operates from a single 5 V supply and provides 17 dB of conversion gain while requiring only 0 dBm input to the integrated LO driver. An IF and an LO amplifier is also included. The ATR0787 incorporates internal matching on each RF, IF and LO port to enhance ease of use and to reduce the external components required. The RF and LO inputs can be driven differentially or single ended. Figure 1. Block Diagram IF_IN+ 8 IF_IN12 9 5 RF_Out+ LO_IN+ 13 LO_IN- 4 RF_Out- Rev. 4588B-SIGE-02/03 1 Pin Configuration Figure 2.
