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
