5V Single-Supply Operation o 60mW Power Consumption o Low-Power Shutdown Mode ________________General Description The MAX2406 low-noise amplifier (LNA)/downconverter mixer is designed for use over a wide range of frequencies and is optimized for communications systems operating at a frequency of 1.
9GHz.
Applications include PWT1900/DCT1900, DCS1800/PCS1900, PHS, and DECT.
This device includes an LNA, a downconverter mixer, and a local-oscillator (LO) buffer in a lowcost, plastic surface-mount package.
At 1.
9GHz, the LNA has 2.
5dB typical noise figure and a -9.
5dBm input third-order intercept point (IP3).
The downconverter mixer has a low 9.
1dB noise figure and a 4.
5dBm input IP3.
Image and LO filtering are implemented off-chip for maximum flexibility.
The MAX2406 has a differential IF port that can be used in a single-ended configuration by tying the unused side to VCC.
The LO buffer can be driven differentially or in a single-ended configuration with only -10dBm of LO power.
Power consumption is 60mW in receive mode, and typically drops to less than 1µW in shutdown mode.
For transceiver applications, the MAX2410 or MAX2411A both offer a transmitter along with a similar receiver.
