GENERAL
The
碌
PC1675G,
碌
PC1676G and
碌
PC1688G are silicon monolithic ICs developed as general-purpose high-
frequency wideband amplifiers.
These ICs are based on the
碌
PC1651G packaged in a 4-pin disc mold. The present ICs are each packaged in
a 4-pin mini-mold suitable for surface mounting on higher density print board. (the
碌
PC1651G has been discontinued).
The features of these amplifier ICs are:
<1> The 4-pin mini-mold package as shown in Figure 1 substantially reduces the mounting area.
<2> The ICs are supplied on an embossed tape conforming to EIAJ鈥檚 鈥淭aping Dimensions of Electronic Components
(RC-1009)鈥? This embossed tape is 8 mm wide, and suits automatic mounting.
<3> The following three models are available, classified by power gain.
碌
PC1675G: G
P
= 12 dB TYP., NF = 5.5 dB TYP. (@f = 500 MHz)
碌
PC1676G: G
P
= 22 dB TYP., NF = 4.5 dB TYP. (@f = 500 MHz)
碌
PC1688G: G
P
= 21 dB TYP., NF = 4.0 dB TYP. (@f = 500 MHz)
<4> All the models can operate at high frequency and in wide band.
碌
PC1675G: 1900 MHz TYP.
碌
PC1676G: 1200 MHz TYP.
碌
PC1688G: 1100 MHz TYP.
