... LO frequency doubler and divider, dual low-noise amplifier (LNA) gain settings, and a low-current paging mode that extends the handset standby time. The MAX2320 family includes six ICs: four operate at both cellular and PCS frequencies, one operates at cel- lular frequencies, and one at PCS frequencies (see Selector Guide) ...

... Detailed Description Low-Noise Amplifier Within its operating bands, each device in the MAX2320 family (except the MAX2327) has three modes of LNA operation: high gain, high linearity (HGHL); high gain, low linearity (HGLL); and low gain, high linearity (LGHL). The logic inputs control the LNA mode as described in the AC Electrical Characteristics ...

... GAIN and LIN logic inputs control the MAX2324’s three operational modes, as summarized in Table 3. MAX2327 Operation The MAX2327 is similar to the MAX2320 except it only features an HGLL mode, and either LO output buffer is selectable during shutdown. It consists of PCS and cel- lular LNAs; PCS, cellular digital, and cellular FM mixers; ...
