RH-18/36/38 Engine module Company confidential CCS Technical Documentation The UEM ASIC mainly handles the interface between the baseband and the RF section. UEM provides A/D and D/A conversion of the in-phase and quadrature receive and transmit signal paths and also A/D and D/A conversions of received and transmitted audio signals to and from the user interface. The UEM supplies the analog signals to RF section according to the UPP DSP digital control.

Company confidential RH-18/36/38 Engine module CCS Technical Documentation Baseband – RF interface The interface between the baseband and the RF can be divided into three categories: - The digital interface from the UPP to the RF ASIC (Mjoelner). The serial digital interface is used to control the operation of the different blocks in the RF ASICs. - The analogue interface between UEM and the RF. The analogue interface consists of RX and TX converter signals.

Company confidential CCS Technical Documentation RH-18/36/38 Engine module General description of the RF circuits In the following general descriptions different colours are used in the block diagram. The GSM 850 signal route is shown in red, the GSM1900 route in green and the common signal lines are shown in blue. Signal lines which is common for both Receiver signal path The signal from the antenna pad is routed to the RX/TX switch (Z700).
RH-18/36/38 Engine module Company confidential CCS Technical Documentation Transmitter signal path The I/Q signal from the BB is routed to the modulators for both 850 and 1900 MHz. The output of the modulators is either terminated in a SAW filter (Z603) for GSM 850 or a balun for GSM1900. Both signals are amplified in buffers. The amplitude limited signal is then amplified in the PA (N700) where the gain control takes place.
Company confidential CCS Technical Documentation RH-18/36/38 Engine module nal. Building blocks for the PLL include: Phase detector, Charge Pump, Voltage Controlled Oscillator (VCO), N-Divider and loop filter. As mentioned earlier only the VCO and loop filter is external to the Mjoelner IC. The VCO (G600) is the component that actually generates the LO-frequency. Based on the control voltage input the VCO generates a single-ended RF output. The signal is then differentiated through a balun.
RH-18/36/38 Engine module Company confidential CCS Technical Documentation Power Supply All power supplies for the RF Unit are generated in the UEM IC (D200). All power outputs from this IC has a decoupling capacitor at which the supply voltage can be checked. The power supply configuration is described in the block diagram below: Figure 16: Power supply configuration The names in bold are signal names used on the RF schematic pages.
