MAX2410 19-1320 Rev 1 3/98 Low-Cost RF Up/Downconverter with LNA and PA Driver General Description Features The MAX2410 performs the RF front-end transmit/receive Low-Cost Silicon Bipolar Design function in time-division-duplex (TDD) communication Integrated Upconvert/Downconvert Function systems. It operates over a wide frequency range and Operates from Single +2.7V to +5.5V Supply is optimized for RF frequencies around 1.9GHz. Applications include most popular cordless and PCS 3.2dB Combined Receiver Noise Figure: standards. 2.4dB (LNA) 9.8dB (Mixer) The MAX2410 contains a low-noise amplifier (LNA), a downconverter mixer, a local-oscillator (LO) buffer, an Flexible Power-Amplifier Driver: upconverter mixer, and a variable-gain power-amplifier 18dBm Output Third-Order Intercept (OIP3) (PA) driver in a low-cost, plastic surface-mount package. 35dB Gain Control Range The LNA has a 2.4dB (typical) noise figure and a LO Buffer for Low LO Drive Level -10dBm input third-order intercept point (IP3). The down- Low Power Consumption: converter mixer has a low 9.8dB noise figure and a 60mW Receive 3.3dBm IP3. Image and LO filtering are implemented off- 90mW Full-Power Transmit chip for maximum flexibility. The PA driver has 15dB of gain, which can be reduced over a 35dB (typical) range. 0.3W Shutdown Mode Power consumption is only 60mW in receive mode or Flexible Power-Down Modes Compatible with 90mW in transmit mode and drops to less than 0.3W in MAX2510/MAX2511 IF Transceivers shutdown mode. A similar part, the MAX2411A, features the same func- Ordering Information tionality as the MAX2410 but offers a differential bidirectional (transmit and receive) IF port. This allows PART TEMP.
