Features (Typical Unless Otherwise Noted) 50dB RF detection range (typical) Support of GaAs HBT, bipolar technology Quad-band operation Shutdown mode for Power Save in Rx slot GPRS compliant External loop compensation option Accurate temperature compensation Frequency range is 450MHz to 2GHz micro SMD package: 1.5mm x 1.5mm x .995mm Description The device is intended for use within an RF transmit power control loop in GSM mobile phones and supports GaAs HBT and bipolar RF single supply power amplifiers. The circuit operates with a single supply from 2.7V to 3.3V. The LMV243 contains an RF detector, error amplifier, ramp V/I converter and output driver. The LMV243 input interface consists of the RF input, Ramp voltage, and a digital input to perform the function "Shutdown/Transmit Enable". The device will be active in the case TX_EN = HI, otherwise, the device goes into a low power consumption shutdown mode. During shutdown the output will be in high impedance (tri-state). A single external RC combination is used to provide stable operations that accommodates individual PA characteristics. The LMV243 is offered in a 8-bump micro SMD 1.5mm x 1.5mm package. This space saving package supports flexible product placement almost anywhere in the circuitboard. Applications GSM mobile phone AGC for digital audio TDMA RF control Wireless LAN

General Description: This board can be used to evaluate National Semiconductors LMV243 Single-Channel, Quad-Band GSM Power Controller. The device is intended for use within an RF transmit power control loop in GSM mobile phones and supports GaAs HBT and bipolar RF single supply power amplifiers (PAs). The key value is its immunity to changes in the PA gain control function. It contains a 50 dB logarithmic amplifier detector and interfaces directly with the directional coupler. The operating frequency range of the device is from 450 MHz to 2 GHz. Evaluation Board Contents: Assembled Board LMV243 Datasheet Application Note 1805
