COSINE Tier-1 distributor Jarwey｜Sub-1G vs 2.4G transceivers COS8820/8830

Jarwey is a Tier-1 distributor of COSINE—selection support, datasheets, sampling & small batch, lead-time coordination.

COSINE Sub-1 GHz / 2.4 GHz transceiver SoCs target smart meters, communication networks, IoT, and connected-vehicle links. The catalog describes an integrated RF front end, LNA, PA, mixers, fractional synthesizer, analog baseband, and power management, with OFDM support. Split the family by band: COS8820 is sub-1 GHz; COS8830 is 2.4 GHz. PLC line drivers are a different path—see the HPLC article.

Product features

Sub-1G / 2.4G transceivers with PA, mixer, and synthesizer; OFDM modem support per catalog.

Applications (vendor-stated)

Smart meters, communication networks, IoT, V2X, and wireless sensing.

Transceiver table

Also listed: TX EVM (−30 dB / −23 dB), unwanted sideband rejection 35 dBc, analog-filter 3 dB bandwidth bins (0.2–1.5 / 0.2–3; unit not printed—confirm on the datasheet).

Checklist before freeze

1. Band / regulation: sub-1 GHz vs 2.4 GHz; regional power and channel masks.
2. Modulation: OFDM required? Does EVM and sideband rejection cover the air interface?
3. Link budget: compression, cascaded NF / IIP3, LO phase noise.
4. Baseband filter: confirm bandwidth unit vs channel BW.
5. Samples: request datasheet and pilot qty from Jarwey.
