5 V-BIAS, +15.5 dBm OUTPUT, 1.8 GHz WIDEBAND
DESCRIPTION
The
PC1679G is a silicon monolithic integrated circuit designed as medium output power amplifier for high
frequency system applications. Due to +13 dBm TYP. output at 1 GHz, this IC is recommendable for transmitter
stage amplifier of L Band wireless communication systems. This IC is packaged in 8-pin plastic SOP.
This IC is manufactured using NEC’s 20 GHz f
nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution and
prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.
FEATURES
• Supply voltage
• Saturated output power
• Wideband response
• Isolation
• Power Gain

    ... V fluctuation. CC The coupling capacitors, connected to the input and output pins, are used to cut the DC and minimize RF serial impedance. Their capacitance are therefore selected as lower impedance against a 50 perform as high pass filters, suppressing low frequencies to DC. To obtain a flat gain from 100 MHz upwards, 1 800 pF capacitors are used in the test circuit. In the case of under 10 MHz operation, increase the value of coupling capacitor such as 10 000 pF ...
