The ADF4108 frequency synthesizer can be used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. It consists of a low-noise digital PFD (phase frequency detector), a precision charge pump, a programmable reference divider, programmable A and B counters, and a dual-modulus prescaler (P/P + 1). The A (6-bit) and B (13-bit) counters, in conjunction with the dual-modulus prescaler (P/P + 1), implement an N divider (N = BP + A). In addition, the 14-bit reference counter (R counter), allows selectable REFIN frequencies at the PFD input. A complete PLL (phase-locked loop) can be implemented if the synthesizer is used with an external loop filter and VCO (voltage controlled oscillator). Its very high bandwidth (8GHz) means that frequency doublers or prescalers can be eliminated in many high frequency systems, simplifying system architecture and reducing cost.APPLICATIONS Broadband wireless access Satellite systems Instrumentation Wireless LANs Base stations for wireless radio

The HMC219B is an ultraminiature, general-purpose, double balanced mixer in an 8-lead plastic surface mini small outline package with exposed pad (MINI_SO_EP). This passive monolithic microwave integrated circuit (MMIC) mixer is fabricated in a gallium arsenide (GaAs) metal semiconductor field effect transistor (MESFET) process and requires no external components or matching circuitry. The device can be used as an upconverter, downconverter, biphase demodulator, or phase comparator from 2.5 GHz to 7.0 GHz.The HMC219B provides excellent local oscillator (LO) to radio frequency (RF) isolation and LO to intermediate frequency (IF) isolation due to optimized balun structures. The RoHS compliant HMC219B eliminates the need for wire bonding and is compatible with high volume surface-mount manufacturing techniques. The consistent MMIC performance improves system operation and assures regulatory compliance with HiperLAN, U-NII, and ISM.Applications Microwave radios High performance radio local area network (HiperLAN) and unlicensed national information infrastructure (U-NII) Industrial, scientific, and medical (ISM)

The HMC305SLP4E is a broadband 5-bit positivecontrol Silicon IC digital attenuator with CMOS compatibleserial-to-parallel driver package in a leadlessQFN 4x4 mm SMT package. Covering 0.4 to 6GHz, the insertion loss is typically less than 1.6 dB.The attenuator bit values are 0.5 (LSB), 1, 2, 4, and8 dB for a total attenuation of 15.5 dB. Attenuationaccuracy is excellent at ±0.25 dB typical with an IIP3of up to +52 dBm. Five bit serial control words areused to select each attenuation state. A single Vccbias of +3.3V to +5V is required.The HMC305S(E) is a replacement for the HMC305A(E), HMC305B(E) and HMC305(E).Applications Cellular Infrastructure Wireless Infrastructure Microwave Radio & VSAT Test Instrumentation
