Silicon Bipolar MMIC 2.5 GHz Variable Gain Amplifier Technical Data IVA-14208 IVA-14228 Features Description • Differential Input and Output Capability • DC to 2.5 GHz Bandwidth; 3.4 Gbits/s Data Rates • High Gain: 24 dB Typical • Wide Gain Control Range: 34␣ dB Typical • 6 V Bias • 5 V VGC Control Range, IGC␣ <3␣ mA • Fast Gain Response: <10␣ nsec Typical • IVA-14208: Low Cost Plastic Surface Mount Package • IVA-14228: Hermetic Ceramic Surface Mount Package The IVA-14 series MMlCs are variable gain amplifiers. The IVA-14208 is housed in a miniature low cost plastic surface mount package. The IVA-14228 is housed in a miniature hermetic ceramic surface mount package. Both devices can be used in any combination of single-ended or differential inputs or outputs (see Functional Block Diagram). The lowest frequency of operation is limited only by the values of user selected blocking and bypass capacitors. 30 VGC < 3 V Typical applications include variable gain amplification or limiting for fiber optic systems (e.g. SONET) with data rates up to 3.4 Gbits/s, mobile radio and satellite receivers, millimeter wave receiver IF amplifiers and communications receivers.
