1 Surface Mount Voltage Variable Equalizer 5Ω 95 to 2 MHz The Big Deal Adjustable attenuation slope Supply voltage from + to + IP3 +55 dbm typical Minimal deviation from linear loss, ±.5dB CASE STYLE: HE1354 Product Overview The is a 5Ω Voltage Variable Equalizer built into a shielded case (size of.394 x.394 x. ).This model offers excellent performance over a wide frequency range of 95 to 2 MHz with the variable slope providing great flexibility in a small mm package. The is often used to compensate RF chain gain flatness or cable loss versus frequency. Key Features Feature Low power consumption: Supply voltage +3- DC at max ma Control voltage - at max ma Adjustable attenuation slope (Control voltage of to ) High linearity (IP3 +55 dbm typ.) Advantages Allows for high layout density of circuit boards, while minimizing affects of parasitics. Allows adjusting the slope to compensate for the precise loses encountered. Low distortion enabling improved system performance. Minimal deviation from linear loss over frequency range: ±.5dB Provides low signal distortion over the passband. Page 1 of 7
