MHL9838MOTOROLA RF DEVICE DATA
The RF Line
Designed for ultra–linear amplifier applications in 50 ohm systems operating in
the cellular frequency band. A silicon FET Class A design provides outstanding
linearity and gain. In addition, the excellent group delay and phase linearity
characteristics are ideal for the most demanding analog or digital modulation
systems, such as TDMA and CDMA.
•Third Order Intercept: 50 dBm Typ
•Power Gain: 31 dB Typ (@ f = 880 MHz)
•Excellent Phase Linearity and Group Delay Characteristics
•Ideal for Feedforward Base Station Applications
•For Use in TDMA and CDMA Multi–Carrier Applications
