The LTC1064-4 is an 8th order, clock sweepable Cauer lowpass switched capacitor filter. An external TTL or CMOS clock programs the value of the filters cutoff frequency. With Pin 10 at V+, the fCLK to fCUTOFF ratio is 50:1; the filter has a Cauer response and with compensation the passband ripple is ±0.1dB. The stopband attenuation is 80dB at 2 × fCUTOFF. Cutoff frequencies up to 100kHz can be achieved. With Pin 10 at V-, the fCLK to f-3dB ratio is 100:1, the filter has a transitional Butterworth-Cauer response with lower noise and lower delay nonlinearity than the Cauer response. The stopband attenuation at 2.5 × f-3dB is 92dB. Cutoff frequencies up to 50kHz can be achieved.The LTC1064-4 features low noise and low harmonic distortion even when input voltages up to 3VRMS are applied. The LTC1064-4 overall performance competes with equivalent multiple op amp active realizations. The LTC1064-4 is pin compatible with the LTC1064-1, LTC1064-2 and LTC1064-3.The LTC1064-4 is manufactured using our enhanced LTCMOSTM silicon gate process.Applications Antialiasing Filters Telecom Filters Sinewave Generators

The HMC1160 is a MMIC voltage controlled oscillator that integrates a resonator, a negative resistance device, and a varactor diode, and features a half frequency output.Because of the monolithic construction of the oscillator, output power and phase noise performance are excellent over temperature.Power output is 12 dBm typical from a 5 V supply voltage. The voltage controlled oscillator is housed in a RoHS compliant SMT package and requires no external matching components.APPLICATIONS Point to point and multipoint radio Test equipment and industrial controls VSAT

The HMC431LP4(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO with an integrated resonator, negative resistance device, varactor diode, and buffer amplifier. The VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure. Power output is 2 dBm typical from a 3V supply voltage. The voltage controlled oscillator is packaged in a low cost leadless QFN 4x4 mm surface mount package.APPLICATIONS 802.11a & HiperLAN WLAN  VSAT Radios  UNII & Point-to-Point Radios
