LMX5453LMX5453 Micro-Module Integrated Bluetooth 2.0 Baseband Controller and Radio | RF and Wireless | 1 | NRND | The LMX5453 is a highly integrated Bluetooth 2.0 compliant solution. The integrated baseband controller and 2.4 GHz radio combine to form a complete, small form-factor (6.1 mm × 9.1 mm × 1.2 mm) Bluetooth node.
The on-chip memory, ROM, and Patch RAM provide lowest cost and minimize design risk with the flexibility of firmware upgrades.
The firmware supplied in the on-chip ROM supports a complete Bluetooth Link Manager and HCI with communication through a UART or USB interface. This firmware features point-to-point and point-to-multipoint link management, supporting data rates up to 723 kbps.
The radio employs an integrated antenna filter and switch to minimize the number of external components.
The radio has a heterodyne receiver architecture with a low intermediate frequency (IF), which enables the IF filters to be integrated on-chip. The transmitter uses direct IQ-modulation with Gaussian-filtered bit-stream data, a voltage-controlled oscillator (VCO) buffer, and a power amplifier.
The LMX5453 module is lead free and RoHS (Restriction of Hazardous Substances) compliant. For more information on those quality standards, please visit our green compliance website at ** http://www.national.com/quality/green/

LMX8410LHigh-Performance Mixer With Integrated Synthesizer | Development Boards, Kits, Programmers | 3 | Active | The LMX8410L is a high-performance wideband (RF frequency input from 4 to 10 GHz) I/Q demodulator with an integrated LO and IF amplifier. With IIP3 of 28 dBm and NF of 15 dB (both at 5GHz), it provides excellent dynamic range for high performance applications. The device offers large complex bandwidth of 2.7 GHz for high data-rate applications.
The LMX8410L offers an automatic DC offset correction algorithm that reduces the offset to less than ±2 mV. Fine control of gain and phase of I and Q channels is enabled using SPI interface to achieve high image rejection.
The LMX8410L has a high level of integration providing high performance while saving board space and complexity. It integrates a wideband RF input balun, eliminating the need for external baluns. It integrates a high-performance PLL and VCO, eliminating the need for external LO and LO driver. The device also integrates an IF amplifier and several low noise LDOs, further simplifying the board.
The LMX8410L integrates a very low-noise synthesizer, with a PLL FOM of –236 dBc/Hz, providing up to 56.5-dBc DSB integrated noise at 5 GHz carrier. The LO allows for phase synchronization across multiple devices. The high-performance synthesizer output can be brought out to drive another stage or a data converter. The integrated LO can be bypassed for applications that share a common external LO.
