  • Integrated circuit having a parasitic resonance filter
    Patent number: 5917233
    Abstract: A packaged integrated circuit configured for interconnection to an external component comprises a die (1) having a high frequency contact (8), the die (1) being disposed on a lead frame (3). The lead frame (3) comprises a plurality of leads (9). At least two of the leads are first and second RF port leads (9a, 9b) which are electrically connected to the RF port. When mounted to a printed circuit board substrate, there is a capacitor (12) connected between the first and second high frequency contact (8) leads (9a, 9b) to achieve frequency specific signal attenuation at an unwanted frequency with minimal contribution of insertion loss at a desired frequency.
