MRFIC1804
MOTOROLA RF DEVICE DATA
The MRFIC Line
1.8 GHz LNA/Downmixer
Designed primarily for use in DECT, Japan Personal Handy Phone (JPHP),
and other wireless Personal Communication Systems (PCS) applications. The
MRFIC1804 includes a low noise amplifier and downmixer in a low-cost
SOIC-16 package. The integrated circuit requires minimal off-chip matching
while allowing for the maximum in flexibility and efficiency. The mixer is
optimized for low side injection and offers reasonable intercept point as well as
high efficiency and 4 dB of conversion gain. Image filtering is implemented
off-chip to allow maximum flexibility. With both TX and RX enable pins low, the
device is in standby mode and draws less than 0.5 mA.
Together with the rest of the MRFIC180X series, this GaAs IC family offers
the complete transmit and receive functions, less LO and filters, needed for a
typical 1.8 GHz cordless telephone.
• Usable Frequency Range = 1.5 to 2.2 GHz
• 14 dB Gain, 2.3 dB Noise Figure LNA
• 4 dB Gain, 13 dB Noise Figure Mixer
• 0.9 dB Mixer Input Intercept Point
• Simple LO/IF Off-Chip Matching for Maximum Flexibility
• Low Power Consumption = 24 mW (Typ)
• Single Bias Supply = 2.7 to 3.3 V
• Low LO Power Requirement = – 5 dBm (Typ)
• Low Cost Surface Mount Plastic Package
• Available in Tape and Reel by Adding R2 Suffix to Part Number.
R2 Suffix = 2,500 Units per 16 mm, 13 inch Reel.
• Device Marking = M1804
