Aeroflex-MicroMetrics MFA series low cost ring quads are designed for high volume applications requiring repeatable wideband performance. An in-house epitaxial process provides control over carrier concentration and thickness, resulting in outstanding lot-to-lot uniformity, superior matching of junction capacitance, and tight forward voltage matching. The MFA series also features low series resistance, low junction capacitance, and low leakage currents. Lower costs are achieved via a unique volume oriented packaging solution, including in-house automated encapsulation and attachment methods. Several low, medium and high barrier models are available in 1,000 piece quantity for $1.99 each. Package types available include a new surface mount ceramic package (CS 17) and standard round ceramic package (CS26R). Custom specs are also achievable at an additional charge.
